Microphone Polluter
AKA as an "MP." Someone who thinks he/she's an MC and that he/she can flow on the mic, but they are wack and in reality they are polluting the microphone with their wannabe rhymes.

Larry: That guy is definitely not an MC, he's a Microphone Polluter with his wack-ass raps about the suburbs.
