Sweat Shirt Friend 

A friend of the opposite sex, who you enjoy hanging out with, but is so unattractive that you prefer they wear sweats and a sweat shirt when you see them.

No man I'd never touch that, she's just a sweat shirt friend.

Sweat T Shirt Contest 

1.) When someone completely soaks their white t-shirt to the point that it becomes see-through.

2.) A direct result of overactive perspiration in an embarrassing public setting.

Dude 1: Hey bro, that was an intense game of b-ball
Dude 2: Fuckin' right dude, I'm totally rockin' a Sweat T Shirt Contest right now.
Dude1: Fuckin' gross, man!

Sweaty Shirtless Rolling Bro's (SSRB's) 

Bros that have taken their shirt off and are dancing like idiots, completely rolled out on ecstasy. Frequently seen at concerts (especially jam band, techno, and electronica shows) and college parties, SSRB's generally kill the mood for any non-bros in the group.

"I had a great time at the concert, but there were way to many Sweaty Shirtless Rolling Bro's (SSRB's). Kinda lame."
