Binge, oddly nude, consumed by drink (6)
I believe the answer is:
bender
'binge' is the definition.
('bender' can be a synonym of 'binge')
'oddly nude consumed by drink' is the wordplay.
'oddly' means one should take alternating letters.
'consumed by' means one lot of letters goes inside another.
'drink' becomes 'beer' (beer is a kind of drink**).
The alternate letters of 'nude' are 'nd'.
'nd' going into 'beer' is 'BENDER'.
(Other definitions for bender that I've seen before include "Non-stop drinking" , "A wild drinking session, sounds twisted" , "Drinking jag" , "Booze-up" , "What might leave one legless" .)
