I was a wee bit bored today, so I thought I'd dick around with the Infected Glitch.
(You spawn and hit "E" very fast and you should appear inside a Survivor)
Anyway, after joining a terribad Versus pub, I did a few Surprise Boomers. (Doing the glitch as a Boomer, and blowing up or spitting on everyone)
Eventually, one of them made a dash to a safe room.
He locked himself in so we couldn't kill him.
I got Jockey, so I figured I'd exploit the situation for lulz. I glitched my way into the Saferoom and Jockey'd him.
Lulz and rage ensued.
(Keep in mind, this was a terribad pub, so griefing the enemy team is okay)
Also, I forgot to record a demo, so I have no video of it.
