Butt Slurp

The ability of ones self to intake substances via the anal cavitity. This is achieved through letting out a turtle head (the tip of feacial excretion from the shitebox) and proceeding to rub the turtle head in the desired substance, i.e, cocaine. The turtle head is then pulled back into the body through a series of anal contractions. This can be a difficult process, but for analy bombarded sluts and gayboys, it proves no challenge.
