Drunk owes me a grand (7)
I believe the answer is:
awesome
'grand' is the definition.
(thesaurus)
'drunk owes me a' is the wordplay.
'drunk' is an anagram indicator.
'owes'+'me'+'a'='owesmea'
'owesmea' is an anagram of 'AWESOME'.
(Other definitions for awesome that I've seen before include "Inspiring fear and respect - or slangily excellent" , "Inspiring reverential respect" , "Instilling wonder" , "Overwhelming or dreadful to behold" , "Dreadful; amazing" .)
