Be an ungracious winner (5)

I believe the answer is:

gloat

(Other definitions for gloat that I've seen before include "Exult over one's good fortune" , "Look like the cat who got the cream" , "Look triumphant" , "Express triumphant self-satisfaction" , "Be full of malicious delight" .)

I've seen this clue in the USA Today.
