The act of giving a wedgie from the front and the rear at the exact same time. Usually and most effectively applied by two people to one person. (Underpants usually ripped upon application of the Melvin.
That melvin we just gave Luke must have ripped his balls, taint, and his asshole, not to mention his tighty whities.

The most annoying motherfucker in the world. He is a total noob at COD. He thinks he can compare to an Andrew, but then the Andrew gives him a bloody nose.

The act of diarrhea-ing on top of someone's head in a tropical climate so that the Melvinee can't wipe it off.
The reason we smell so bad isn't because of our foray through the jungle. It's because Carruthers decided to drop a steaming Melvin on us...again.
