Wet tops spoiling dance (3,4)

I believe the answer is:

two step

'dance' is the definition.
(I know that two-step is a type of ballroom dance)

'wet tops spoiling' is the wordplay.
'spoiling' indicates an anagram.
'wet'+'tops'='wettops'
'wettops' with letters rearranged gives 'TWO-STEP'.

(Another definition for two step that I've seen is " dance".)
