What does the greatest mc mean?

Question

i mean i hear it all the time and rappers always say im the greatest mc no rude comments bou how da h**l u aint no that

Answer 1

It means "move the crowd",but it's mostly linked to rappers not to circus freeks or even bloody rock stars , "MC" is a really stupid and senseless way to put together an acronym and not that many people people try to look it up it so don't expect to be made fun of.

Answer 2

heres the definition, sounds correct...............

Mc- (mək)

regarded as being inferior, trivial, monotonous, etc. and hence undesirable this Mcnewspaper
