  • British Parliamentary: In BP, knifing refers to making arguments that refute or directly contradict arguments made by your same side in the debate, most commonly refering to the back half speakers responding to the front half. Knifing may or may not be highly penalized by judges, depending on the expectations set at a given tournament. Knifing is never rewarded and should be avoided when possible.
