It's not limited to gaming, but the way "rape" is so casually thrown around these days makes me want to puke. CGI popping up in old movies or losing in an online game should NEVER EVER be compared to such a horrifying and traumatic experience. Just the other day I heard someone say adding easier difficulties to Dark Souls would be to "rape the game" and I just wanted to savagely beat that person. Oh man, now I'm all riled up.
MMO slang and all those weird acronyms are annoying as hell too. You can tell straight away if someone has played way too much World of Warcraft, since every other thing they say is a three- or four-letter acronym. An old friend of mine came up to me and said he found Diablo 3 to be a huge disappointment, since "you can't do unseen TP on HC, LOL". I had no clue what he meant and I'm not sure I wanna know either. Best thing was when a customer at work asked me if it was true that all "Xbox 720" (ugh) games would be "soulbound". Yeah.
