Canadian Pipeline 

The Canadian Pipeline, not to be confused with the Alaskan Pipeline, is when two people each insert the end of a straw or tube into their butt. Then one of them farts, causing the air to travel into the others ass.

Alex: Hey dude, wanna canadian pipeline with me? I had chili for dinner.
Derek: No thanks, you might shart into my ass.

Canadian Pipeline 

An advanced sexual technique in which the female lays on her back with her legs folded over her head. The male then lays on the female's legs and inserts his penis into her snatch. The male then uses his arms on her legs to move up and down. The male does not pull out and directly transfers his fluids into her pussy.

Melisa: Jordan gave me a Canadian Pipeline last night, it was so kinky!!!
Jim: What the hell! I thought you and I had something special you fucking whore!!!!
