Drunk takes bottle opener to bingo (6)
I believe the answer is:
blotto
'drunk' is the definition.
(thesaurus)
'bottle opener to bingo' is the wordplay.
'opener' indicates taking the first letters.
'to bingo' becomes 'lotto' ('lotto' can be a synonym of 'bingo').
The first letter of 'bottle' is 'b'.
'b'+'lotto'='BLOTTO'
'takes' acts as a link.
(Other definitions for blotto that I've seen before include "under the table" , "Unconscious from drink" , "Blind drunk" , "Slangily drunk - ready to bolt" , "Totally drunk" .)
