Dance, pervert! (5)
I believe the answer is:
twist
I believe this is a double definition.
'dance' is the first definition.
(twisting is a kind of dancing)
'pervert' is the second definition.
('twist' can be a synonym of 'pervert')
(Other definitions for twist that I've seen before include "Wind around like Dickens' Oliver" , "Bend round; dance" , "Unexpected event" , "Strong thread" , "See 1" .)
