Wife/Girlfriend Aggro: "Aggro" is itself a game term, used on boss fights (when you're getting "aggro" from the bad guy it means he's focused on attacking you).
Hard as it may be to believe, sometimes a WoW player may have a significant other who does not play WoW. Sometimes this person (usually female in these cases) tends to be a crazy, unreasonable harpy who wants their husband/boyfriend to spend time with them sometimes instead of going on WoW raids all night.
"Sorry, guys, my girlfriend's being unreasonable again."
When these demands become extreme, sometimes the raider will joke to his fellow raiders that he has "pulled wife aggro" and has to go appease that crazy broad.
The WoW World is Plagued by Sexual Deviants
Like any online community, WoW has its share of perverts. One particularly odd manifestation of this is people approaching Night Elf female characters--that's these things:
...and offering WoW gold to take off their clothes and dance. Why they can't make their own Night Elf female character, take off its clothes, and dance, is going to have to remain between them and God because we don't really want to know.
Incredibly, WoW's programmers didn't seem to anticipate any of this and so the game doesn't give players a lot of ability to perform any sexual actions. But horny people with lots of spare time can get pretty creative.
Apparently male night elves have two penises.
Then there's the Deeprun Tram, an automated tram running between two major WoW cities, which has gained a reputation as a place for perverts to secretly have cyber sex (and sometimes they get caught, as relayed in this infamous tale).
Probably the most famous WoW pervert went by the character name "Bronze Mustache". Whether this is some kind of porn reference or not, we don't know, as we don't really know much about the intricacies of the Chinese language.
Googling "Bronze Mustache" is much safer than "World of Warcraft Sex Pervert."
This WoW soap opera carried out among some Chinese players is pretty long and convoluted, but the basics are that "Bronze Mustache" stole another guy's wife, "Quiet Moon", and the Chinese WoW community became so upset over it that there were mass server-crashing protests eventually culminating in a mass in-game suicide:
Their sordid tale is recounted here, including original posts from the aggrieved husband and international newspaper accounts. Sample chat log:
Finally there's this thoughtful blog post and discussion about in-game sex that offers some insights possibly better left unexplored. From the comments:
"On my server in particular we had a swingers guild, where the players would meet with each other IRL, slam it, and then return to their regularly scheduled lives. There were women characters, played by women , that were known to be cyberers. I had more than one girl actually want to call me up and have phone sex. More than one naked photo sent to me.
So what am I trying to say? Through it all, MMO's are sometimes a very clear mirror of Real life."
