look up any word, like dirty sanchez:
 
1.
(noun) a wanabee dj; preferably a dj that mixes music with 2 computers or 2 boom boxes instead of an actual mixer &/or turntables.

Many professional DJs & MCs started off as pre-DJs before they got their equipment.
Guy #1: I like the music of this dj!

Guy #2: Well, technically speaking, he isn't a real DJ, but a pre-DJ. All he's doing is just lowering the volume of one song on one boom box & raising the volume of the other boom box. DJs tend to have alot of equipment, but he's just using 2 boomboxes.
