Replenish beer that’s drunk? Disgraceful (13)
I believe the answer is:
reprehensible
'disgraceful' is the definition.
(thesaurus)
'replenish beer that's drunk?' is the wordplay.
'that's drunk?' is an anagram indicator (I've seen 'drunk' mean this).
'replenish'+'beer'='replenishbeer'
'replenishbeer' anagrammed gives 'REPREHENSIBLE'.
(Other definitions for reprehensible that I've seen before include "Deserving rebuke" , "Deplorable" , "Worthy of blame" , "Blameworthy" , "Disgraceful" .)
