Speaking without thought; talking like an un-educated person on a subject they know nothing about; giving an answer to a question that has no relevancy to the question; Sean's cousin Bob gave a Mumble Jumble answer (not Mumbo Jumbo Dr. Bob).
Bob gave a Mumble Jumble answer to Sean's simple question about a fishing trip.

Also known as a soundcloud rapper, many go by Lil’ (name) and all end up with face tattoos.
They only rap about drugs, money (even if they don’t have it), gangs (whether or not it’s true) and use random beats found on YouTube.

They make up their own words and are hard to understand, they repeat the same lyrics throughout their songs and can be heard using the words; uh, yeah and aye a LOT.

Garbage subgenre of Hip Hop music that grew to be popular in the 2010s. Mumble rap is usually a bunch of drugged up morons mumbling incoherent garbage. Most of their "songs" are about sex, drugs, or money and they all sound the same.
Mumble rap isn't music, it's garbage. I can't wait until it goes out of style.
