Makes fun of in a playful way (6)
I believe the answer is:
teases
'makes fun of in a playful way' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for teases that I've seen before include "is tantalising" , "baits" , "'Makes fun of, playfully (6)'" , "Provokes in playful way" , "Attempts to provoke through persistent annoyance" .)
