Oddly boozy young man (3)
I believe the answer is:
boy
'young man' is the definition.
(a boy is a male child)
'oddly boozy' is the wordplay.
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
The alternate letters of 'boozy' are 'BOY'.
(Other definitions for boy that I've seen before include "Male child" , "Youth" , "Lad" , "Son" , "Young male" .)
