Fatheaded own goal due to bad visibility (3)
I believe the answer is:
fog
'bad visibility' is the definition.
'fog' can be an answer for 'visibility' (thesaurus). I'm not sure about the 'bad' bit.
'fatheaded own goal' is the wordplay.
'fatheaded' becomes 'f' (this could be a standard abbreviation of which I'm unaware).
'own goal' becomes 'OG' (football abbreviation).
'f'+'og'='FOG'
'due to' is the link.
Can you help me to learn more?
(Other definitions for fog that I've seen before include "Bafflement" , "Confusion" , "Bank restricting visibility" , "Impenetrable mist" , "Heavy mist" .)
