Something that's supposed to match up to actual hip-hop, like MF DOOM, but the real meaning is Young Money Cash Money... then a B...
Idiot: OMFG! YMCMB IS BEST RAP.
Logical individual: For starters, "YMCMB" isn't even rap, it's hip hop since it focuses more on lyrics then beats, also, there are many hip hop artists who can beat someone like Lil' Wayne at everything, since he is a unintelligent fool.
