"Two in the pink, one in the stink and the thumb to make her cum." This was originated by Backstreet Law and is accompanied by a hand gesture where only the ring finger is down. It is also associated with the line, "Put your motherfucking nose in the hose...SEATBELT!!!"
I took that bitch home last night and gave her the seatbelt. At first, she was surprised, but then she kinda liked it.
