MUS
A male student often refered to as a prized item, when in reality they are nothing more than a dirty redneck southern pride douche bag. They like to sit in class and play the biscuit game with each other and enjoy loosing. The boys here are really gay and they like to eat cake. Often times you can find them at Backstreet down in midtown, Memphis performing all kinds of fellatio. These mussies tend to get it in the arse atleast, but not stopped at, 6 times a day.
That kid is gay, he must go to MUS, or atleast attended it once in his lifetime.

Wow did you see that fag run away!? He goes to mus!
