Be taunted about young girl in society (9)
I believe the answer is:
debutante
'young girl in society' is the definition.
(girl debuting in upper-class society)
'be taunted about' is the wordplay.
'about' indicates anagramming the letters.
'be'+'taunted'='betaunted'
'betaunted' with letters rearranged gives 'DEBUTANTE'.
(Other definitions for debutante that I've seen before include "Maiden speaker" , "socialite" , "Young woman entering society" , "girl coming out" , "Society girl" .)
