Drink a lot, being reckless (5)
I believe the answer is:
binge
'drink a lot' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'being reckless' is the wordplay.
'reckless' is an anagram indicator.
'being' with letters rearranged gives 'BINGE'.
Can you help me to learn more?
(Other definitions for binge that I've seen before include "Immoderate indulgence" , "Prolonged drinking session" , "Self-indulgent session" , "Drunken orgy" , "A drinking bout" .)
