I believe the answer is:

hula

I'm a little stuck... Click here to teach me more about this clue!

'dance' is the definition.
(hula is a kind of dance)

I don't understand how the rest of the clue works.

(Other definitions for hula that I've seen before include "Hip-swaying dance of Hawaii" , "Hoop spun around the body" , "Hawaiian dance - kind of hoop" , "Hawaiian rain dance" .)

I've seen this clue in the Evening Standard.
