Omega Mu 

A fat chick or a fatty posse. Derived from the fat girl sorority Omega Mu in the movie Revenge of the Nerds. The Omega Mu plumpers help the nerds such as Takashi, Wormser, Poindexter, Lewis and Gilbert, Lamar Latrell and Booger combat the jocks and cheerleaders and they put on a concert and take control of the campus.

"Look at that big fat fatty in the short skirt and tight, low cut top!"

"What an Omega Mu!"

Omega Mu Gamma 

(abbreviation: OMG)

1. A stereotypical sorority girl who frequently speaks in abbreviations such as "OMG," "LOL," "FBO," "totes," "presh," "biffel," "bestie," "abbrevs," etc.

2. Any girl (who may or may not be a member of a sorority) who considers herself "totes obsessed" with any or all of the following:
-the color pink
-shoes
-chocolate
-any major brand name
-The Notebook
-The Hills
-Twilight
-her betches! lawlz!!!11

3. The universal community of females who fit either of the aforementioned descriptions.

“Girl: What are the different sororities on campus like?
Guy: I dunno, they’re pretty much all Omega Mu Gammas.”

"Girl 1: Was Paris Hilton ever in a sorority?
Girl 2: I don't think she went to college, so I doubt it, but she's definitely an OMG."

"Guy 1: At first I thought she was a cool chick; then I realized she was an OMG.
Guy 2: How's that?
Guy 1: She was wearing a Patriots jersey, so I figured she was into football. I tried to start a conversation about sports, and then she went on and on about how she's 'totes obsessed' with Tom Brady. I tried to bring it back to sports by arguing that the Dolphins are still the only team ever to have a perfect season. Then she wouldn't shut up about Jason Taylor, but she said he's no Edward Cullen. Who does he play for?"

Sigma Alpha Mu (Beta Omega) 

The most bad ass bunch of mother fuckers you will ever meet. The number one Greek organization on their campus and quite possibly the entire world. No one is even close to being Sigma Alpha Mu.

Man I wish I was cool enough to be Sigma Alpha Mu (Beta Omega)!
