The African Exchange Student 

The act of sitting on someone else's butt and proceeding to poop into their asshole. Usually used as a form of foreplay, together they pass it back and fourth from person A's asshole to person B's asshole, then back to person A's asshole. This may go on all night long.

Dude 1: "Hey, did you get laid with Rachel last night?
Dude 2: "Yeah man we did the African Exchange Student for hours. It was kinky as hell."
Dude 1: Hell yeah! I've always wanted to try it but I don't think my asshole is wide enough to accept the poop yet."

The Stinky Exchange 

The Stinky Exchange consists of a male and a female. This process starts with the man taking a mondo dookie while the female rides his penis as the female also proceeds to defecate into the gap inbetween his legs into the same toilet.

Man-“Damn I need to shit so bad, but I’m also really horny.”
Girl-“Same, let’s do the Stinky Exchange.”

The Beggar's Exchange Rate

When someone doesn't follow the international exchange rate and takes you for a ride. Usually common among people who have no money.

So I was in Montreal for the weekend, and I couldn't find a Bureau de Change anywhere. The only person I could find was this complete mess of a man looking in trashcans for lunch.

I asked him "can you make change?" and I showed him a fifty dollar bill U.S..

I got back five dollars Canadian.

I was given The Beggar's Exchange Rate.
