What a bunch of fucking noobs do in Call of Duty: Modern Warfare 2. It involves putting on danger close, marathon, and commando and running around and knifing. However, before going 'knifing', the prick (another term for javelin glitcher) cooks a Semtex, and without letting go of RB (or if you have no freinds and play ps3 R1) they hit Y and switch to the javelin. Somehow, this makes them just explode when you kill them. Needless to say, it is extremely frustrating and chances are it has accounted for many dollars in propert damage (ie. broken controllers).
Guy 1: dude what the fuck? I just shot this kid and I blew up?! What?
Guy 2: oh that's the javelin glitch. Don't worry, they will patch it soon and then all the kids who can't get kills will be hopeless.
