As Warcraft is a 3D game with a virtual world and free-moving characters, there are occasional things you can type to make your character say something amusing or move a certain way. One of the most popular of these is...
Your character begins to perform a dance limited by race and gender (all of the same race-gender makeup have the exact same dance). The action breaks upon movement.
In the upcoming expansion, we have been promised Dance Studios -- places in the virtual cities to learn NEW dances! This is incredibly exciting, especially for players who like to customize their characters (such as people on Role Playing realms).
SOMETHING TO DANCE ABOUT!
My husband found a blue post on mmo-champion about the dance studios -- they will be implemented in a patch after Wrath's release, but there's some new info about how they work.
New dances will be added in a content patch, one of the objective (sic) with the dance studio isn't to just add new dances but also let players combine moves to create their own dance. (source Blizzcon fansite summit, bolding mine)
This is better than I thought it would be. I'm completely excited, and the only thing to make this better would be if they fixed the ugly new hair styles the same way they fixed Sylvanas Windrunner (see image). I hold out hope for reasonably awesome hair.
I guess the big question is -- what kind of dance do you plan to put together? Birdfall is not really a dancer, so I'd like to give her something a little awkward and lame. And Dustfire is a bit of a "bad girl" so she'd have a dance that'd inevitably embarrass me in front of my guild. But my druid is big and sweet and enthusiastic, so she'd have an innocent but FUN dance.
