Drunk reluctant to part with money (5)
I believe the answer is:
tight
I believe this is a double definition.
'drunk' is the first definition.
(slang term)
'reluctant to part with money' is the second definition.
(I've seen this before)
(Other definitions for tight that I've seen before include "corked?" , "Constricted - intoxicated" , "Stingy; drunk" , "Drunk, firm, concise" , "Taut" .)
