'glaswegian drunk' is the definition.
The definition suggests a past participle verb which matches the answer.

'distribute beer to old' is the wordplay.
'distribute' indicates anagramming the letters (I've seen this in other clues).
'beer'+'to'+'old'='beertoold'
'beertoold' with letters rearranged gives 'BLOOTERED'.
