Beings out on sprees (6)
I believe the answer is:
binges
'sprees' is the definition.
(I've seen this in another clue)
'beings out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'beings' with letters rearranged gives 'BINGES'.
'on' acts as a link.
(Other definitions for binges that I've seen before include "Prolonged drinking sessions" , "Bouts of overindulgence" , "Bouts of excessive and prolonged drinking" , "In slang, excessive drinking sessions" , "Beings in drinking sprees" .)
