Crash -- female cut (4)
I believe the answer is:
flop
'crash' is the definition.
(thesaurus)
'female cut' is the wordplay.
'female' becomes 'f' (abbreviation).
'cut' becomes 'lop' (lopping is a kind of cutting).
'f'+'lop'='FLOP'
(Other definitions for flop that I've seen before include "Fall limply - box-office failure" , "Total failure; fall heavily" , "Fail" , "Community cards in poker" , "Fall clumsily, liked failed play" .)
