vainglorious

If you admire yourself in the mirror all the time and constantly brag about all the beauty contests you have won, you might rightfully get accused of being vainglorious.

A vainglorious attitude is not very likable in a person and can be annoying to be around. Vainglorious people are vain, excessively boastful, and have swelled pride. The base word, vainglory, dates all the way back to the 14th century and means “worthless glory.”
