Cheeky pundit playing with me (8)
I believe the answer is:
impudent
'cheeky' is the definition.
(I've seen this before)
'pundit playing with me' is the wordplay.
'playing with' indicates anagramming the letters.
'pundit' with its letters mixed up with 'me' makes 'IMPUDENT'.
(Other definitions for impudent that I've seen before include "impolite" , "Cheeky, disrespectful" , "Lippy" , "Audacious" , "Impertinent, insolent" .)
