Brag

I don't like to listen to her brag about her job all the time.

Her brag about her beauty was seen as arrogance by others.

His brag of never losing a game was proven wrong in the tournament.

She couldn't resist a good brag about her new car.

His brag of being able to solve any problem turned out to be empty words.

She made a brag about her extensive knowledge of history during the class discussion.
