Although I don’t exactly know what Goth dancing is, I’m pretty sure that the female undead dance was taken from female deadheads dancing at Grateful Dead shows.

I always thought these two were sync’d up versions of ‘Doin da butt’ – course I can’t find any source video that’s close

Human:
Male: John Travolta, Saturday Night Fever
Female: Macarena, while drunk

Night Elf:
Male: Michael Jackson, Bille Jean
Female: Alizee

Dwarf:
Male: traditional Cossack dance (I was wrong, the “Gopak” is Ukrainian and is the one where the dancers do vertical leaps while kicking outward)
Female: Riverdance, traditional Irish dance

Gnome:
Male: modern disco
Female: modern salsa
(no one can find the source videos for these which is probably why it wasn’t in this video)

Draenei:
Male: Daler Mendhi, pure awesomeness
Female: Belly dancing (Wowwiki credits it to Shakira)

Orc:
Male: MC Hammer, “Can’t Touch This”
Female: Modern hiphop (Wowwiki credits it to Juvenile’s backup dancers in “Back that azz up”)

Troll:
Male: Capoeria
Female: Shakira, “Whenever Wherever”

Undead:
Male: Headbanger
Female: Goth

Tauren:
Male: “Raise the Roof”
Female: Electric Slide

Blood Elf:

Female: Korean teen imitating Britney Spears (as seen in video)

Wowwiki has some source videos (some of which are out of date) linked here: http://www.wowwiki.com/Dancing

.. How in the world did you know that’s what it was called? That’s a Jeapordy! question in the making right there.

Incidently, I googled “russian dance sit kick”.. Guess what site came up first? It must be reassuring to know you’ll get traffic for oddly-phrased trivia questions.

“..is already done by male dwarves.”

Gah! Completely forgot about that.. Even after watching it… The mind slips with age and all…
