What is the buttock?

A buttock is the rear end of the human. This is where most of your waste and feces come out, when I say feces that means crap by the way, in case your microscopic squishy weak brain could not very well comprehend, this word means understand, my rather larger words. The buttock is made up of 2 slabs of fat (if you will) with a single crack dividing the cheeks. So let me break it down for you in simple terms. You just divide it up. BUTTock.
