obnoy
Obnoying is when someone is so annoying and obnoxious that they turn your day from okay to absolute hell.
My teacher is obnoying. She talks to the ceiling like it's her best friend.
My neighbor’s dog is obnoying. It barks at 3 a. m. and eats my homework.
My friend’s new obsession with memes is obnoying. He sends me 10 of them every hour.
