For those who have played World of Warcraft for a decent time know how the /dance emote works. It is a pool of like 3 different dance moves specific to that race and play them out in random order for an infinite amount of time.

Like for example, you have regular old Dance, then Robot, and Sexy Dance. The game will randomly pair them into a sequence that lasts forever.
D > R > SD > D >SD > R > D > SD > D > D > R > SD (ect ect)
Something to that effect. This allows you to continue dancing and not having to reactivate emotes.
