DJ at a club/party/reception who doesn't play songs people request to him after saying that he would.
"nobody tells dj request what to play. let them tell you what to play, they lose respect for you. they lose respect for you, you lose control. not today." reference from the movie live hard sell hard
person : hey can you play like a g6 by far east movement?
DJ: yeah sure! i'll play it right after this song!
-30 minutes pass by without the song ever being played-
person: fuck you dj request.
