1. A very boastful and talkative person; a braggart
2. A self-important egomaniac who likes to toot his own horn, like those assholes who put bumper stickers on their cars that say "PROUD PARENTS OF AN HONOR STUDENT AT (blah blah blah) HIGH SCHOOL"
"Did you catch the State of the Unionspeech last night? What a fucking blowhard!"

Blowhard
an opinionated person who talks loud and way too long on the same subject, often sensationalizing the subject matter
1. a person that's insecure with their existence, and by their own virtue, they feel the need to blatantly spew ilk and diatribe about other people that are otherwise innocent.
A pompous, self-righteous individual, the kind who, on being charged with non-compliance with Covid regs by not wearing a face covering, flunks the exemption test by blowing hard into the spirometer.
'This guy's an obvious blowhard - we'll send him for a lung function test.'
