Masculine outlook is butcher (6)
I believe the answer is:
mangle
'is butcher' is the definition.
(I've seen this before)
'masculine outlook' is the wordplay.
'masculine' becomes 'm'.
'outlook' becomes 'angle' (as in a journalist's angle on a story).
'm'+'angle'='MANGLE'
(Other definitions for mangle that I've seen before include "Squelchy washing squasher" , "Mutilate badly; wringer" , "Old-fashioned clothes dryer" , "Old device for wringing clothes" , "Clothes-wringer for leg-man" .)
