Local creeps -- they might leave you under the table (3-6)

I believe the answer is:

pub-crawls

'they might leave you under the table' is the definition.
(under the table can mean drunk)

'local creeps' is the wordplay.
'local' becomes 'pub' (one's local pub).
'creeps' becomes 'crawls' ('crawl' can be a synonym of 'creep').
'pub'+'crawls'='PUB-CRAWLS'

I've seen this clue in The Telegraph.
