Stuffing for tortilla won kudos -- that's upset pedant (4-3)
I believe the answer is:
know-all
'pedant' is the definition.
'stuffing for tortilla won kudos that's upset' is the wordplay.
'stuffing for' says the answer is hidden in the clue.
'that's upset' is a reversal indicator.
'llawonk' is hidden within 'tortilla won kudos'.
'llawonk' back-to-front is 'KNOW-ALL'.
(Other definitions for know-all that I've seen before include "One supposedly omniscient" , "Person who thinks he has all the answers" , "Wise guy" , "Smart Aleck" , "Smarty-pants" .)
