Emcee

[Rihanna]

noun; Ehm-Cee.
Derived from the original abbreviation MC, now used as the generic term for anyone who speaks over a beat, or performs songs that could be termed hip-hop. Afrika Bambaataa and his contemporaries at the Universal Zulu Nation were the first to exemplify this term.
Originated as a term for the only individual at a party who could speak on the microphone while the DJ (Disk Jockey) was looping the hook or the beat. Various individuals claim that MC stands for the following:
1: Master of Ceremonies, generally the speaker presiding over a formal gathering, or the host of a Jamaican gameshow.
2: Move the Crowd. Originally proclaimed by the legendary emcee Rakim (of the group Eric B. and Rakim) on his 1986 urban hit Eric B. Is President; to Rakim, an MC was any rapper who was able to control the crowd that he was presiding over.
3: Microphone Controller.
4: Mic Checka
Et cetera.
