when you take your dick and rub it in her crack so shit gets on it and then she licks it off
i just gave this girl an ass swipe
The art of swiping one's ass across a surface with a smooth diagonal motion. Used when dancing and when you have to use an ID to get in a door. Especially when you are too lazy to get the ID out of your wallet.
"Hey Al, could you open the laundry door for me?"
"Sure man, I'll just Ass Swipe it for ya!"
