A Morning After Tee Shirt is when you where the tee shirt of the last person you had sexual intercourse with the next day to work or school.
Girl 1: Ew. Why are you wearing that ugly boys shirt?

Girl 2: No. It's my Morning After Tee Shirt from Dan.

Girl 1: Oh. Makes more sense now.

He: No, baby, that's his credit score!

A girl who is always bummy; she always wears reunion tee shirts-- either current or from years ago. Usually with the tee shirt, she will wear bad-fitting jeans (even mom-jeans look better'n the ones this girl wears). Also, he hair is never done. She is usually ugly and has no charm whatsover. She just throws on anything to cover up-- never mind the fit or the size or the gender it's made for; she might be called an offie; she'll never be called a belle-laide or jolie-laide.
Marleigh: I don't dress too dressy, yet I don't dress too bummy. I'm right in the middle. My "bummy" is never as bummy as Reunion Tee Shirt Girl.

Sue: Yeah, you'd never catch me looking like the REUNION TEE SHIRT GIRL. My bummy-ness goes as far as jeans and a v-neck, fitted tee.

Marleigh: Yeah, shoot me if I ever get like Reunion Tee Shirt Girl

These are considered the cheaper version of the already horrifically douche tee shirts made by Affliction. They are typically worn by 30 something males that want to appear tougher than they actually are. They believe it makes them seem more cutting edge and cooler than the average male. This guy is typically about 30, slightly balding, semi buff (but on the far side) living with several high school buddies and in a relatively dead end job. They may also be a small time drug dealer or bookie! They like to constantly relive the big "scores" of yesteryears and target chicks that are 20-22. Typical first names could be Chad, Chris, Tom, Eric, and Paul. Nicknames could include, Pipes, T-man, Pulli.
