Tormenting (7)
I believe the answer is:
teasing
'tormenting' is the definition.
(teasing is a kind of tormenting)
This is the entire clue.
(Other definitions for teasing that I've seen before include "Making fun of in a playful way" , "Ribbing" , "Mocking" , "flirting maybe" , "Making fun of (someone)" .)
