Female everyone has to ridicule — a scapegoat (4,3)
I believe the answer is:
fall guy
'a scapegoat' is the definition.
(I've seen this before)
'female everyone has to ridicule' is the wordplay.
'female' becomes 'f' (common abbreviation).
'everyone' becomes 'all' (all people).
'has' means one lot of letters go next to another.
'to ridicule' becomes 'guy' ('guy' can be a synonym of 'ridicule').
'f'+'all'+'guy'='FALL-GUY'
(Other definitions for fall guy that I've seen before include "Dupe" , "Scapegoat" , "Aunt Sally" , "Patsy" , "who's not 18 [UPRIGHT]?" .)
