The sound comes from Coming to America, the 1988 Eddie Murphy comedy in which Murphy appears as Randy Watson, frontman of the fictional soul band Sexual Chocolate. The band's flamboyant stage act became one of the film's most quoted sequences, and short clips of their performance have circulated for years as reaction audio and meme soundbites. Its staying power comes from that mix of genuine soul polish and knowing comedy: it sounds impressive enough to sell a grand entrance, while viewers familiar with the film also hear the joke behind the swagger.
