One-Eyed Elephant 

When a man gets on all fours and spreads his asscheeks apart revealing his asshole. With the buttcheeks representing the large ears, the asshole as the one eye, and the hanging cock as the trunk, the lucky viewer gets an image of an elephant with one eye.

Nick: Hey wanna see a one-eyed elephant?
Slut: Sure Daddy.
Nick: There it is. Now tongue that ass like you do so well.

one and done 

A highly popular term, used by a kid named Steve, that translates to a QUICKIE.

1. A chance to fuck a random woman spontaneously, and immediately leave her (while she sleeps, perhaps?)

2. Faking your way through a relationship so that you can score in bed and LEAVE. Good night!

"One and done! GOODBYE. NEXT! Movin' along." -Steve (Not used in a real-life situation)

One in the chamber

when a man has a piss and doesn't shake properly, so that when he puts his penis away he dribbles down his leg. Especially embarassing if wearing grey pants.

"Whats that on your pants, did you spill something?"
"No, I still had one in the chamber"
"oh"
