Before I joined DL, my in game nick was DJ_HI_TEC, which I use in many games. It's from the Die Antword video Zef Side, where they introduce the members of the band. DJ HI TEC is the fat guy with a "PC Computer" who makes next level beats. I took one look at his beautiful fatness and fell in love. Thus, I adopted his name.
In game, I'm DL_HI_TEC, which still gets the point across without the ridiculousness of "DL_DJ_HI_TEC".
