Mmeeep! 

More of a sound than a word.

Used when something is extreamly funny or awkward.

Two girls walking through Wal-Mart and a big fat lady walks by them in a super revealing outfit.
Girl one: "OMG look at that lady."
Girl two: "Mmeeep!"
*both girls bust out laughing*

Meeep 

A very handsome man on the ESPN NFL general board.

Many female posters (including myself) have openly admitted their love (both emotionally and sexually) for Meeep. I have travelled to his home just go get a glimpse of him in his underwear through the window (mind you this is a 1500 mile journey). I wish to marry him someday

Wow, Meeep. is a goregous slice of man meat.
