DirtBike

Instead of motorboating a girl's boobs, you do it in between her ass cheeks.

1)"What would you call a motorboat in between a girl's ass?"
"A dirtbike"
2) "Bro, Claire let me dirtbike her last night!"
3) "Her ass just makes me want to dirtbike her!"

So it turns out, Shit Faced and Dirtbiking are the same thing. Heeheehee

Is that shit on your lips or are you just happy to see me?
