MM

MM is the short form of Much Music, Canada's version of MTV. It plays more music than MTV, yet is somehow a lot more ghetto. Perhaps it is because they hire somebody off of the street every year as part of their Search?

Person 1: I was watching MM's Punk Show yesterday, and they played a fucking Emo band!
Person 2: Yeah, MM is ghetto.
Person 1: And pumo.
Person 1 and 2: SO NOT RELLIN!
