A popular game mode in worms, a strategy computer game in which the player leads a squad of worms in turn-based battles using bizarre weapons like the Concrete Donkey or the Banana Bomb. In this game mode you are given three worms (depending on the number of people who play), and you start with only infinite ninja rope with infinite repeat swings and infinite parachute. You can only get weapons from crates which materialize on the map, one each turn. The main rules to this style of play are attack from the rope (unless the type of weapon prohibits this), abbreviated afr; collect a crate before attacking, cba; attack all but the person in last place, abl; and kill the cow (the noob or person who violates the rules), ktc. Usually all these rules are implemented in play unless otherwise stated by the host.
Don't you know the rules to shoppa, you filthy little cow? I'll kick your bloody arse to smithereens!! Bloody hell!
