When a guy forgets to use deoderant and prematurely perspires in sweaty situations. The more concerned the guy is about the sweat, the more sweat he's going to generate. And if it happens once, it could happen again and again....
Steve: Dude I prematurely perspired watching this smokin chick lick an icecream...

Matt: Dude were you wearing deodarant?

Steve: It was bad dude, I hate premature perspiration.
