9. P.O.S.
Post Orgasm Stupidity - After an orgasm often times one's brain does not function at a high level. Basically being stupid after getting off, or being speechless.
Last weekend, while house sitting I experienced P.O.S. by forgeting to dispose of the condom wrapper before the owners returned.

1. P.O.S.
Used as a subsitute for the saying "Piece of shit"

Describes a not so appealing object or person.

Does not always need to have "a" before "P.O.S." in short, you don't need to say "Thats a P.O.S." you can just say, "Thats P.O.S."
"Dude, that chick looks like P.O.S."

"That smells like P.O.S."
