I've actually made several in-game friends that started out as a simple "how're you doing that?". But, before I got to my 60s (1 bub from 68 now) I always got the 'noob' (to which I reply 'yep'), or 'cheater', and stuff like that. I also get /cheers from a lot of people now, including Alliance (mainly shaman, go figure). Another funny thing is "Bur" (what Horde sees when Alliance says "lol") and I just type 'bur' back, without turning off my keyclone. All 5 shaman saying bur makes for a funny screenshot.

What I find extremely amusing is the Alliance who watch me for a bit (such as the 70 rogue the other day in Terrokar, when I was 64), figure out which one is the 'leader', and attack her, thinking it'll screw me over. He attacked, caught 4 em/trink/cl and a forest of fire nova totems. He didn't bug me after that

There's also the 70 huntard (not a hunter) who kept attacking me in Nagrand the other morning, and dieing every time. I got about 12 hks from her. Couldn't ever figure out what her deal was.
