Drunk; tense (5)
I believe the answer is:
tight
I believe this is a double definition.
'drunk' is the first definition.
(slang term)
'tense' is the second definition.
(similar in meaning)
(Other definitions for tight that I've seen before include "reluctant to buy a round?" , "Mean; tipsy" , "Drunk; giving little room" , "Close - drunk" , "Drunk - under control" .)
