I remember flipping out once playing...shit I can't remember the name of it. It was a scifi based MMO, where you are the people who have populated a new planet. All your powers had to do with nanomachines and stuff. Classes like Doctor and Soldier. Anyway, I honestly don't know what was wrong with me that day, all I can say i was a teenager, and I think heavily into my drug use days at the time, and lots of other factors worked towards me being fairly unbalanced at that time. But this girl in my guild, was talking to me out of character, just typical guild chatter. Another girl joined the conversation, and asked if i was from the south. To which I responded "yes", because I am. and she said "howdy!

" And...I just lost it. I...really have no excuse, but I just went off on her, both barrells, for no fucking reason. "Not everyone here says howdy ok?! We don't all drive trucks and fuck our sisters!" blah blah blah. It really was crazy on my part, but as I've aged, I've come to terms with the idea that I very likely was mentally unstable back then. Given my family history, and in particular my brother and father. I look back on the shit I did then and it boggles my mind, how I survived a lot of it, and came out relatively decent and well adjusted. For the most part, I've always been an easy going guy, but I had some spikes of pure, hormone laced insanity back then that make me feel shame. And that was one of them.
Examples I've witnessed of people raging online? Hmmm, the only one I can really remember was in Payday 2.
I joined a random group, and we were doing a map. No big deal, everyone was playing nice, typical friendly banter at the start. Then one guy starts talking to me "Hey, you are such a fucking hacker" "Hmm? Are you talking to me?" This genuinely puzzled me, because I don't like cheating, and when I've been in missions with people who clearly have hacked Payday 2 for personal gain, I log out of the mission. "Yeah you! You're such a fucking cheater man!" "Um...why do you say that?" Even the other people in the team were like "What makes you say that? He hasn't done anything." "Your Infamy rank!" *blinks* "What about it?" "You can't get that high a rank without cheating! You're a fucking hacker!" "Uh, dude, I worked damn hard to get Infamy IV, I didn't cheat shit" "Bullshit man! There is no such thing as Infamy 6!" "......" "Dude, learn your fucking roman numerals before you start slinging shit like that." *couple minutes later, presumably after he learned the difference between roman numerals 4 & 6* "...my bad bro"
It was funny, but also sad on so many levels.
Oh! Not sure this would be considered raging, as it was mostly in character, and made sense for Everquest. But me and a guild mate, playing on a PVP server. I was a wood elf rogue, he was a dwarf rogue. We made an effort to actually learn Dark Speech, so we could converse with the traditionally evil races. Then, we went out and farmed dark elf meat off a particular group of dark elf npcs, and cooked them into dark elf steaks. Then we went into the zone that connects the...I think it was Western Commons? Maybe Eastern Commons, to the Dark Elf/Troll starting area. We stayed hidden, and started shouting out in the /shout and i think /general channels, in Dark Speech "Selling Dark Elf Steaks!! Fresh off the grill! HUGE stock that must sell now!" The amount of responses we'd get was amazing. "You filthy elf/dwarf! I will gut you and wear your entrails as a necklace!" and other choice comments. It was great fun. Though since nobody ever actually /whispered the rants at us, I always assumed it was in character, which is fine.
