The right rhyme for 'drunk' (5)
I believe the answer is:
tight
'for drunk' is the definition.
(slang term)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for tight that I've seen before include "Hard to undo or open" , "Trim" , "Snug" , "Inebriated" , "Close-fitting; drunk" .)
