Mumble rap is a "sub-genre" of rap that involves people with no vocal talent whatsoever who have to rely on auto tune to make their voice sound somewhat decent which is usually way overdone to the point where they sound like robots, you can barely understand what they're singing about (hence the name "Mumble Rap") and when you search up the lyrics they are mostly about banging hoes, bragging about money and other dumb things. They also can't help but put "lil" in front of their stage name (ex: Lil Pump, Lil Uzi Vert).
