A slang word used in Gears of War to describe a person being chainsawed in half. Also used as an alternative name to the lancer, AKA: Bonesaw Gun
*you sneek up on an unsuspecting enemy, pull out the lancer, get the chainsaw going and then yell:* BONESAW!!!!!!!!!!!!! and thus they have been bonesawed.
