The act of pushing a poop out so that it is sticking about a quarter to half way out of your hole, Make sure it doesn't break or fall out. You can usually tell how big your shit is going to be. Then suck it back up your hole really fast. It brings you a choice feeling. Try it sometime.
Best if you have a nice fat log brewing.
I enjoy an anal poop every once and a while and I am not gay.
