Iajutsu Duel: A move possessed by some samurai-type characters. The samurai puts away his sword, looking deceptively vulnerable. When the hapless opponent moves in for the kill, the samurai whips out his katana with lightning speed, slicing his assailant to ribbons. This move was pioneered by the revolutionary game Bushido Blade, but some other fighting games have re-implemented it since. The name comes from the CCG Legend of the Five Rings, where a card by this name initiated a duel between two samurai.

Kharmic Strike: When two opponents kill one another simultaneously. This term was originally from the card game L5R.

Milk the Eye: A rather unique winning condition from the card game Fluxx.

Tap: To turn a card in play 90 degrees clockwise, indicating that its special power has been used up. The opposite of tap is untap. Wizards of the Coast popularized this concept with their ground-breaking CCG, Magic: The Gathering. Unfortunately, WotC apparently copyrighted the words "tap" and "untap" as well, forcing other CCGs to use some weird synonyms, such as "bow/straighten", "turn/unturn", "engage/disengage", or even "crank/uncrank". No CCG player actually uses these words; the only meaningful word for tapping is "tap".
