Behave smugly (5)

I believe the answer is:

gloat

(Other definitions for gloat that I've seen before include "Crow over" , "Express triumphant self-satisfaction" , "Exult over one's good fortune" , "Take malicious satisfaction" , "Dwell on with self-satisfaction" .)

I've seen this clue in the Evening Standard.
