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."
