This will be updated as I go
A is kill, B is kill, X is kill really hard: Standard advice given to new players of the game. Someone said it once and it stuck.
Airthrow: aY, a throw attack performed in midair against an opponent in front of your character.
Attack teleport: A teleport move that has the character make an attack immediately when they arrive at their destination. ‘hard’ attack teleports actually force the attack (Shikamaru’s <AA or <AB), ‘soft’ attack teleports chain into the attack (Asuma’s <A).
Awakened Hinata: Hinata after her <X modechange. Named after a character that used to be in the game something like 6 iterations ago.
Back B: The attack <B, which on most characters has a significant number of guard frames and is intended as a kind of counter thrown out when blocking a chain.
BALLOOOOOON: Raikage and Bee’s aA, also called “Bellyflop on a Ninja” and “Yo Baby!”
Big One, The: Naruto’s X special. Named after the awful voice acting in Clash of Ninja Revolution 3.
Birds, The: Sai’s vX special and ^A, particularly in desperation.
Blockstun: The period after blocking an attack where your character is uncontrollable.
Chain: A sequence of attacks performed by pressing the B or A buttons in quick succession. Would be called a ‘natural combo’ in another fighting game.
Combo: Linking together a chain, special, or throw is a ‘combo’. For example, most characters can go from the chain BB into the special X.
Cutscene special: A special consisting of an unblockable attack that triggers a cutscene when it lands. Every character has at least one cutscene special. Contrast ‘field special’.
Desperation: Additional abilities gained by characters when they’re low on health. Every character has a ‘desperation percentage’ ranging from 10% to 30%. Once they’re below that amount of health, they start glowing and get powered up in some way. For example, at 30% health, Shino’s bug attacks drain chakra even when blocked. Sometimes called ‘passive abilities’ or ‘latent ninja powers’.
Did I Just Kill A Gay Clown?: Kakashi’s Sharingan Special. Comes from Yu-Gi-Oh Abridged. Alternately, ‘Mind Crush’.
Down Y: The throw vY, a throw some characters have as an alternate to their standard Y throw. Down-y throws can have a different range, a different trajectory, and different damage outputs to the Y throw.
Field special: A special that performs an attack on the main play area, no cutscene involved. Usually costs less than a cutscene special, often blockable.
Gary: The character Naruto. ‘Angry Gary’ is Naruto after his back-X modechange into two-tailed form, ‘Super Gary’ is the character Sage Naruto, and ‘Mister Gary’ is the character Minato. Comes from a long-ago joke about what the Naruto dub was going to be like before it was dubbed.
Gate: Either Orochimaru’s <X counter special or Lee/Guy’s <X modechange.
Gate crash: An attack performed as part of a mode-change special, with the archetype being Lee/Guy’s <X. Often gate crashes have very high priority or invulnerability frames, lots of knockback, but very little damage.
Give Him The Stick: Itachi’s X special, particularly an older variant of it. Comes from a parody of a G.I. Joe PSA.
Go Go Gadget Arms: Kakazu’s vA, >A, ^A, and aA, all of which involve shooting his hands at someone and then pulling them back via the threads attaching them to him.
Grappler: A character that wins by having lots of power armour, unblockable moves, and throws. Grapplers are similar to pressure characters, but instead of looking for a hole by throwing out lots of options, grapplers usually make a hole by requiring different defensive approaches than normal. Examples include Raikage and Choji.
Hair: Jiraya’s <A move.
Hitbox: The part of your character that can be hit by attacks
Hitstun: The period after an attack hits you where your character is uncontrollable and not blocking.
Hominiyoma!: Jiraya’s vA, “Yomi Numa”. Comes from the voice acting.
Hurtbox: The part of your character or another object that can hit another character to cause damage during an attack.
Hyuuga cancel: Cancelling certain moves of by pressing the Y button during their startup. Can only be performed by Neji and Hinata.
I Have A Dog: Ritual incantation upon doing literally anything as Kiba. Comes from the tendency for Akamaru to hit people from offscreen when they think they’ve got Kiba. “Did you know I have a dog?” *dramatic pause* Akamaru interrupts special.
If This Doesn’t Make Me Any Money, I’m Not Interested: Ritual incantation upon selecting Kakuzu. Comes from his horrendous voice acting in the english dub and a previous game in the series.
Invulnerability frames: Frames during an animation where your character cannot be hit by attacks at all. You don’t block the attack, it just goes right through you to no effect.
Jumping The Shark: Jumping over the top of Kisame’s vX special.
Kazuzu: The character Kakazu. Comes from an EVAC member not being able to remember Kakazu’s name.
Kunai deflection: Reflecting thrown kunai back at their source by flicking the C-stick just before they connect with your character. Characters can deflect kunai even if they’re coming from behind, or even while performing a move or during movelag. Kunai that have already been deflected can’t be deflected. Only the standard kunai and needle projectiles can be deflected.
Modechange: A move that changes the character’s properties, usually by changing what moves they have or how much damage they do. Sometimes reversible, sometimes not, often a special. Examples include Lee’s gates, Naruto’s two-tailed transformation, Anko’s curse seal, Kakashi and ANBU Kakashi’s Sharingan, and Hinata’s awakening.
Movelag: The period after performing a move where your character is uncontrollable. Chains are performed by entering the appropriate input during movelag.
Moving to Trieste: Betraying someone, usually by agreeing to gang up on someone with them and then attacking them when their back is turned. Comes from a game of Diplomacy played by EVAC members.
Politics: The reasoning used to determine who to attack in a 4-player FFA, the art of influencing that reasoning. Particularly relevant when one player has been eliminated. Strategies include pointing out which players have a win (and therefore will win the entire match if they win again), which players have more health (and therefore are more of a threat to win if they’re not chipped down), and which players are more skilled (and therefore need to be taken down a peg).
Power armour: A move or action has ‘power armour’ if taking damage doesn’t put the character into hitstun while they are performing the move. Often characters take less damage if they take damage in power armour as well. Examples include Choji’s A, half of what the Raikage does, and Sasori when he’s walking.
Pressure character: A character that wins by getting in their opponent’s face (or grille). Usually does that by being fast, throwing out lots of moderately-safe attacks with a variety of options for followups, or threatening to do lots of damage if the opponent slips. Examples include Hinata, ANBU Kakashi, and Lee.
Puppet: A secondary character on the field that can be commanded by the main character or just does its own thing. Usually only used of persistent or nearly-persistent ones – if it’s just part of an attack the term isn’t usually used. Examples include Kankuro’s puppets, Chiyo’s puppets, Kiba’s dog, and Kisame’s water clone.
Show’s Over: Granny Chiyo’s X special.
Sidestep bullshit: Blocking an attack from behind by sidestepping the frame before it hits you. ‘Sidestep nonsense’ or ‘Sidestep block’ is the PG version.
Size of Africa, The: Description of Jiraya’s down-A when he’s in desperation. Comes from a listing all the character’s desperation abilities.
Skilltachi: The character Itachi.
Special: Move inputted with the X button. Usually takes chakra to perform.
Storylined: Hitting a character with a special that was used on them in the actual storyline of Naruto. For example, hitting Kisame with Guy’s Morning Peacock is storylining.
Teching: Cancelling another player’s throw by pressing any of the attack buttons, or cancelling another player’s attack by hitting it with an attack of your own. Throw-teching throws both players away from each other, but with attack teching both players can continue their chain. You can’t tech throws from behind, but you can tech airthrows, even if you’re in hitstun.
Teleport wars: When one player escape-teleports out of another player’s attacks, and the attacking player attempts to respond, by sidestepping, jumping, continuing the chain, or escape-teleporting after getting hit.
Throw to airthrow: Comboing a character’s Y or vY throw to aY.
Turtle character: A character that wins by defending effectively until the opponent slips, and then piling the hurt on. Usually does that by having powerful chains, combos or specials that have slow leadins, fast interrupting moves or wide area of effect moves. Examples include Gaara and Kisame.
Two gates or go home!: Ritual incantation upon someone selecting Lee. Comes from an old EVAC member’s playstyle.
Wakeup special: Hitting a character with a special as they’re getting up from the ground. Usually performed by making sure the special’s hurtbox is inside them after the invulnerability frames end.
Weeaboo Fighter: Naruto Shippuuden Gekito Ninja Special.
Zoning character: A character that wins by controlling their opponent’s movement, often by throwing out attacks with high priority, weird hitboxes, large areas of effect, or that just come from a strange angle. Sometimes have a puppet or similar effect. Examples include Deidara, Shino, and Kankuro.
