Obbist
An Obbist is like a nerd with a secret life. They’re usually harmless, but if you mess with them, they’ll make your life a living hell.
My teacher said the Obbist in the back was going to fail the whole class if he didn’t stop staring at the ceiling.
My brother got in trouble with an Obbist because he laughed at his joke.
I saw an Obbist crying in the hallway, and I just walked away.
