When you have anal sex and afterwards your ass leaks out the left over cum. Then the cum and the leftover poop mixes together. Eventually you wipe the ass off with whatever is around,(sometimes your own hand) leaving you with a "poonukkle"
This guy was banging me in the ass last night, and the poonukkle afterwards smelt like fried cheese.
