Need to take things like a man? Opt out! (11)
I believe the answer is:
kleptomania
'need to take things' is the definition.
(compulsion to steal)
'like a man? opt out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'like'+'a'+'man'+'opt'='likeamanopt'
'likeamanopt' with letters rearranged gives 'KLEPTOMANIA'.
(Other definitions for kleptomania that I've seen before include "Compulsion to steal" , "Impulse to steal" , "urge to help oneself" , "Recurrent urge to steal" , "Stealing urge" .)
