I was in SM last night after trying to kill the horseman, and was in the "lobby" (where all the instances are) with about 5 other horde killing Alliance as they entered. The pile of skellies was something to be proud of

Anyways, a new group of horde comes in to zone in. I see in /say: ewwww, dual boxer (this is after all the cheers and love from the horde I'm 'defending' SM with)

He then /says I hate dual boxers!

Me: So leave.
Him: Get bent
Me: Oh, you're a tough guy (he then zones)

Everybody else was laughing. Moral of the story, either ignore it or come up with a witty comeback. Just don't curse or harrass them, they're probably baiting you to be reported. I do report them when they curse, it just shows their true immaturity.
