• adjective (smugger, smuggest) irritatingly pleased with oneself; self-satisfied.
I know Tweety Bird is a male - but this reminds me of a friend of mine when I saw her Sunday afternoon. She was being very smug about her Saturday night, and then changed her 'toon' to " what me I did not do anything?" "why what did you hear?"
This was a guy friend Sunday morning. He declined to tell me what he was smug about - but he definitely could not stop smiling.
I am happy that my friends all had good Saturday nights. I am not jealous and I am not comparing my Saturday night to theirs: as mine only included a craw fish boil and an engagement party filled with smug couples. I think I was the only single attendee - but at least I made the effort to go.
Back to my smug friends. The definition includes "self Satisfaction" (nothing wrong with self satisfaction) but it also implies that one feels like they are better, smarter or more fortunate than the person who they are acting smug around; which is not a very 'friend-like' approach not to mention irritating...
I think that someone Bragging is less insulting than a person acting smug.
• verb (bragged, bragging) say something boastfully.
