 The current record for fastest rapper is held by Spanish rapper Domingo Edjang Moreno, known by his alias Chojin, who rapped 921 syllables in one minute on December 23, 2008.In the late 1970s, the term Emcee, MC or M.C., derived from the term master of ceremonies, became an alternative title for a rapper, and for their role within hip-hop music and culture.An MC uses rhyming verses, pre-written or ad lib ('freestyled'), to introduce the DJ with whom they work, to keep the crowd entertained or to glorify themselves.
