Radar for race issues, allowing one to sense a racist, racism, etc, in their immediate vicinity. Sometimes this racedar can be all wrong, but sometimes right on. Usually physically manifests itself as a "gut feeling".
My racedar told me that when the White guy in the truck with the Confederate flag on the back called me his "Nigga" he did not mean "friend".
computer jockey (as opposed to DJ or disc jockey). comes from the theory that, since many DJs no longer spin actual vinyl, and the spinning of CDs on CDJs may even wane in the future towards complete use of sound files, the title of the DJ should also change to represent the shift in our culture towards all digital media, and to indicate the ending of the "disc" era.
while some might argue that it doesn't matter if one spins actual discs in order to have the title DJ, others argue that the distinction between CJ and DJ gives due respect to those who paved the way by learning the arduous processes involved in wax manipulation.
...and tonight we have a special guest for you. CJ Skribble on the keyboard rockin the house!
