Obstropolous
A person who acts like they're special just to make everyone else feel stupid.
My boss is obstropolous. He made me do a presentation on the color blue just to show off.
My friend is obstropolous. She called me a ‘boring human’ just because I didn’t text her back.
My teacher is obstropolous. She turned a simple test into a 10-question quiz just to be mean.
