Can't stand, as the drunk (5)
I believe the answer is:
hates
'can't stand' is the definition.
(I've seen this before)
'as the drunk' is the wordplay.
'drunk' indicates anagramming the letters.
'as'+'the'='asthe'
'asthe' with letters rearranged gives 'HATES'.
(Other definitions for hates that I've seen before include "passionate feelings" , "Loathes" , "Dislikes intensely" , "Despises" , "Detests" .)
