Stretched three sheets to the wind? (5)
I believe the answer is:
tight
'stretched' is the definition.
(I've seen this before)
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 "Miserly or blotto" , "Taut" , "Close - drunk" , "Hard to undo or open" , "Parsimonious" .)
