A loser who continuously posts You-Tube music video links in a chatroom or other chat forum to make others think he is a true music afficiando. He does this to bolster his low self-esteem (as if he's performing a real technological feat) and to make the others in the forum think he's capable of doing more than his usual "Hello" "How are you?" and of course, his obligatory "lols". Chatroom DJs are also prone to dole out huge amounts of worthless information on any given subject.
"Dude, did you see that cretin posting all those music links"? "Yeah, he's just a chatroom DJ".
