Acronym standing for Make-Up Caked, Open-Mouth-Gum-Chewing-Cool-Girls.
Stated by William Beckett (lead singer of The Academy Is...) on his blog, this is an acronym that can be used to describe all the girls who think they're amazing and "S0 HAWTT!11" but really aren't. Also see preps.
Gosh, I'm so sick and tired of all the MUCOMGCCGs around here.
