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)!

Mu-Beta 

A group of the wildest, trealist people you will ever meet. They are loved because they do what they want, and the fact that they hate being tested.

If you want to be Mu-Beta, you've got to balance the lifestyle of a skoal-dippin David Allan Coe fan and that of a wanna be businessman.

And one thing is for sure: if you ask them to, Mu-Beta's will f****n DO IT!!!

Are you testing my Mu-Betaness???

I hear that Mu-Betas are the wildest on Fairview Avenue.

Watch that metal thang, Bird....I heard dem Mu-Betas in town and up to no good.
