Stop going over my head, dance! (5)
I believe the answer is:
stomp
'dance' is the definition.
(stomp is a kind of dance)
'stop going over my head' is the wordplay.
'going over' means one lot of letters goes inside another.
'head' says to take the initial letters.
The first letter of 'my' is 'm'.
'stop' placed around 'm' is 'STOMP'.
(Other definitions for stomp that I've seen before include "tramp" , "Dance (with heavy stamping?)" , "Walk heavily" , "Tread very heavily" , "Fast rhythmic dance" .)
