You were in math class. Another boring day, like always.
Your teacher motions to the board with their dry erase marker. "Alright, class, can anyone tell me what 134 / 2 is?"
There was a pretty snarky, douchey kid in your class named Mason. He adopted this strange catchphrase- 'six seven'. He'd randomly say this 'six-seven' thing in a super annoying, exaggerated drawl with a hand motion as if he were weighing two options. It drove you absolutely nuts, but other kids seemed to feed off of it...
Until today. To your very horror, Mason raised his hand (to give a most likely incorrect and satirical answer)... but it didn't stop raising. It kept raising... till it hit the roof... but Mason was still sitting in his desk. His eyes rolled to the back of his head, revealing the red nerves underneath, as his jaw seemed to completely unhinge, revealing an insane amount of white teeth and a stretched out mouth. In a low, distorted scream that sounded like it was straight from hell,
"SIIIIIX SEEVEEEEEEEEEEEEENNNNN!!!!!"
As soon as he let out this inhuman screech of an answer, the lights in the classroom suddenly went out.
