I must be doing something wrong as a GM -- my players have never actually killed any other character in a Champions game except by accident...maybe because I design their characters?
Here's a few more from my group's lingo:
Picked Up The Spare -- Tactic of one character mowing down multiple targets with an area of effect or explosion attack and another character with roughly the same speed (usually another energy projector) picking off any who are still standing after the initial attack. [From bowling terminology]
Brick Missile -- Any unusually large or heavy object which can be (more or less) easily picked up and thrown by the bricks in the party. Places where large numbers of such objects are readily available (such as car dealerships, a typical junkyard, construction site, etc.) are called Brick Gardens.
Brick Frisbee -- A manhole cover. (See Brick Missile)
Sheet Metal (Scrap Metal) Giftwrap -- The act of leaving an unconscious enemy bound or otherwise restrained in a temporary prison of metal debris for the authorities.
Skip -- Name given to any character (friendly or enemy) who suffers the indignity of being knocked back into a (usually large) body of water.
