A term used to diss rappers that some say make incomprehensible and/or meaningless music. The term is thrown around mainly by nerds that think they know everything about music.
Person 1: You're a Mumble rapper.
Rapper: What makes me a Mumble rapper.
Person 1: I only listen to intellectual music, I hate you, and I have 5000 IQ.
