The Scissor Bone is the mechanism responsible for the tapering and chopping off of dangling turds from the bottom. The Scissor Bone can also be used to hold back farts and, if the owner has a very strong Scissor Bone, it can be used to prevent anal rape.
My boyfriend slipped it in the wrong hole last night, I think he broke my scissor bone, I can't seem to hold anything back...
