Bachelor faces disaster defending the ladies? (3)
I believe the answer is:
bog
'the ladies?' is the definition.
(bog is an informal term for the toilet)
'bachelor faces disaster defending' is the wordplay.
'faces' says to take the initial letters (I've seen 'face of' mean this).
'disaster defending' becomes 'OG' (own goal, defending error in football).
The initial letter of 'bachelor' is 'b'.
'b'+'og'='BOG'
(Other definitions for bog that I've seen before include "Swamp" , "Peaty area" , "Morass" , "Peaty wetland" , "Slough" .)
