Doin' It is a 1996 single by American rapper LL Cool J, taken from his 1995 album Mr. Smith. Built around a sample of Grace Jones' My Jamaican Guy, the track became one of his best known hits for its smooth groove and call and response hook. The 'doin it well' phrase has since been clipped from the chorus for memes and edits, where its confident refrain works as a shorthand for doing something skillfully, looking good while doing it, and knowing it.
