MC
In the late 1970s, the term MC (master of ceremonies) also known as that of the rapper, became associated with the role in hip hop music and culture. An MC uses rhyming verses, whether pre-written or freestyled, to introduce and praise the DJ he or she works with, to hype up the crowd, to pay homage to his own stature, or to comment on society. As hip hop progressed, the title MC has been thought to mean a number of acronyms such as Microphone Controller, Mic Checka, Music Commentator, and one who Moves the Crowd, notably through Rakim's lyrics on the matter ("Eric B. easy on the cut and no mistakes allowed/ 'Cuz to me, 'MC' means 'move the crowd'"). Some use this word interchangeably with the term rapper, while for others the term denotes a conception and demonstration of the role indicative of skill and of connection to the wider culture, while the latter term does not.
