A DJ that appears to suffer from ADD due to his/her inability to allow any single song to play for more than 30 seconds.
Dude, this song RULES! (15 seconds later.....) What the FUCK? What happened to the second verse? Damn ADDJ!

Oh Christ, looks like we got another ADDJ in this club.

Are you SERIOUS? This ADDJ is playing an AC/DC medley?
