Obnoctoid
A human being so annoying they probably woke up one day and decided they were going to be the worst person ever.
My mom is an obnoctoid. She texts me at 3 a. m. with 10 emojis and a question about my love life.
My coworker is an obnoctoid. He talks to the coffee machine like it’s his best friend.
My dog is an obnoctoid. He barks at the mailman like he’s been wronged for 100 years.
