A sexual act, usually performed between 2 males. The guys link their assholes together as close as they can. The one guy then shits directly into the asshole of the other guy. It's fucking gross and these 2 guys, Jeff W. and Brian K. claim they did it. I then shot them both.
"Hey Jeff, what do you want to do tonight? Anal, Oral, Necro???" asked Brian in a voice too homo for words.

"Naw, let's have a good old fashioned "Shit Swap" replied Jeff, his beedy pig-like eyes twinkling

"A shit swap?!!!?? I'll grab the plastic sheets and the laxative!!!!" exclaimed Brian, in a fake manly voice.

When a man is having sex with a woman and is about to do his dizzle. He shits in his had and shoves it up her vagina and says baby I gotta go. Then leaves. She thinks that he shot a big load. Because she can still feel it. But hes already gone home and when she wakes up she sees shit everywhere.
I did the shit swap, she aunt getting pregnant. Shit Swap.

A fecal foreplay game that involves the act of pooping into another persons anus; preferably of a solid nature. The goal is to pass the poo as many times possible without letting it slip out and hit the ground.
I met this girl on craigslist who had a serious poop fetish. We played a few games of Sphincter Shit Swap before getting into grimy, unprotected anal sex. I beat her 12-5.
