Occasionally smelly hooligan in successful show (4-3)
I believe the answer is:
sell-out
'successful show' is the definition.
(a show which has sold all its tickets)
'occasionally smelly hooligan' is the wordplay.
'occasionally' indicates alternate letters.
'hooligan' becomes 'lout' (both can mean an aggressive person).
The alternate letters of 'smelly' are 'sel'.
'sel'+'lout'='SELL-OUT'
'in' is the link.
(Other definitions for sell-out that I've seen before include "Betrayal" , "When all tickets are booked in advance" , "Event with no further ticket availability" , "successful show" .)
