Mean drunk (5)

I believe the answer is:

tight

I believe this is a double definition.

'mean' is the first definition.
('tight' can be a synonym of 'mean')

'drunk' is the second definition.
(I've seen this before)

(Other definitions for tight that I've seen before include "Secretive, drunk (colloq.)" , "corked?" , "Difficult and problematic" , "Miserly or blotto" , "Mean - drunk" .)

I've seen this clue in The Independent.
