Nasty Matt 

An overwhelmingly disgusting, and sometimes funny male named Matt. Who roams myspace hitting on and insulting females. He bakes "e-cookies" or whatever. Also he spams the myspace chat rooms like an immature little child.

I hope Nasty Matt doesn't come and spam this chatroom.

Matt Nasty 

When you're having sex with a fat person, you slide your penis inbetween their folds of fat until you climax into the belly button.

Person A: "You had sex with someone THAT fat?!"
Person B: "Yeah! It gave me the chance to do a Matt Nasty!"
