The imaginary fraternity that members of the Spartan Marching Band say they are apart of.

Sweet, you're a sigma mu beta girl eh? Where's your house?

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)!
