Spot a skinhead getting a kiss (5)
I believe the answer is:
speck
'spot' is the definition.
(thesaurus)
'a skinhead getting a kiss' is the wordplay.
'a skinhead' becomes 's' (head letter of 'skin').
'getting' means one lot of letters go next to another.
'a kiss' becomes 'peck' (I've seen this before).
's'+'peck'='SPECK'
(Other definitions for speck that I've seen before include "Small spot" , "Small mark" , "Bit of dust" , "Italian ham" , "lot of fat in school?" .)
