Draw attention away from happy male on ecstasy (7)
I believe the answer is:
upstage
'draw attention away from' is the definition.
(I've seen this in another clue)
'happy male on ecstasy' is the wordplay.
'happy' becomes 'up' (I've seen this in other clues).
'male on ecstasy' becomes 'stage' (I am not sure about this - if you are sure you should believe this answer much more).
'up'+'stage'='UPSTAGE'
Can you help me to learn more?
(Other definitions for upstage that I've seen before include "Divert attention from another as actor might in play" , "Outdo" , "Take attention from (another actor)" , "Divert attention from another as actor may" , "Stand-offish (sl.)" .)
