Frats Pins and Buttons

Omega-Mu is a sorority at Adam's College. The Omega-Mu's have a reputation around the campus as being pigs, which Booger believes but has a complete turn around once he meets them. This is also the motivation for the Alpha-Beta's and Pi Delta Pi's prank during the Tri-Lamb's party. The Omega-Mu's team up with the Lambda Lambda Lambda's for the homecoming carnival. A new generation of M's appear in the third movie, which Booger uses to show the new Tri-Lamb's how to have a good party.
