Drunken spree (6)
I believe the answer is:
bender
'drunken spree' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for bender that I've seen before include "Bout of heavy drinking" , "A drinking spree - no wonder one is twisted" , "Slangy drinking spree - crooked result?" , "Drinking jag" , "Non-stop drinking" .)
