Fellow fan coming back looks silly (4)
I believe the answer is:
naff
'looks silly' is the definition.
I know nothing about this answer so I can't judge whether this works.
'fellow fan coming back' is the wordplay.
'fellow' becomes 'F' (abbreviation - of a society etc.).
'coming back' is a reversal indicator.
'f'+'fan'='ffan'
'ffan' in reverse letter order is 'NAFF'.
Can you help me to learn more?
(Other definitions for naff that I've seen before include "Vulgar and tasteless" , "Showing lack of taste" , "pants" , "Rubbish" , "Socially boorish; inferior" .)
