This came, of course, from the GMod Idiot Box, Episode 1 (And later, Episodes 2 and 4)
Ever wonder how Dr. Hax managed to have those monitors fly seemingly out of nowhere? Ask no more! His personal propguy was carrying the HAAAX!
The HAAAX is a large launcher, armed with Computer Monitors. Upon firing, the monitor will fly forward, smiting hackers with the cruel punishment they deserve. Able to do 50 damage with the slow, bouncing projectile, the HAAAX is made for close-quarters firing. It can also tumble the aflicted, preparing the ragdolled blockhead for a second volley.
Just don't foget the battlecry when going after all them cheaters.
HAAAAAX!!!
