Refuse time spots (5)
I believe the answer is:
trash
'refuse' is the definition.
(thesaurus)
'time spots' is the wordplay.
'time' becomes 't'.
'spots' becomes 'rash' (I've seen this before).
't'+'rash'='TRASH'
(Other definitions for trash that I've seen before include "Refuse, waste" , "Waste material (US)" , "Rubbish, litter" , "Refuse; destroy" , "American refuse" .)
