Octopussiest
Someone who squishes their face and yell like they're arguing with a donkey in the middle of a math test.
I did octopussiest during my math test because I couldn’t figure out what 7 times 8 was. I failed.
My friend did octopussiest in the hallway and got sent to the principal’s office.
My neighbor does octopussiest every morning at 6 a. m. It’s annoying.
