Mysterion 

Mysterion is the superhero alter ego of Kenny McCormick! He’s wearing a purple cape with a hood and a question mark on his head. He’s wearing a purple shirt with a letter M on it, a pair of purple pants and an underwear on top! His power is that he can’t die, because if he dies he will wake up in his bed. And he’s basically the batman of South Park!

Mysterion: *dies*
*in kenny’s room*
Toolshed: Dude, Kenny, what'd you run away for?! We've gotta fight these guys!
Mosquito: Yeah, come on, get your costume on, lazy-ass!

Mastering Chemistry 

A website created to make the lives of American college students a nightmare through the use of nazi-like grading on significant figures and rounding throughout 15+ pages of hell. Commonly referred to as a bitch for changing 1 number in each person's given values to piss people off.

"Hey have you done the Mastering Chemistry for this week yet?"

"No but I heard it's a real killer."

"Yeah I tried the hints and couldn't even work through those!"
