American Diabolism 

A reverse uno version of American Exceptionalism, where the United States of America is by definition uniquely evil, imperialist, and chauvinist.

To support Vladimir Putin and Xi Jin Ping is to suffer from American Diabolism.

Call me an American Diabolist, but I don't think the CIA should install more puppet dictators in Latin America

diabolical lick 

That trend on TikTok.
A person or people steal an item from school sneakily (commonly out of the bathroom) and post a video of it on any social media platform. (e.g. toilet, soap dispenser, urinal screen)

(I'm serious about the toilet) + It is also called devious lick.

Friend A: Hey, wanna hit a diabolical lick?
Friend B: Bet.
*2 hours later*
(principal) Intercom: "IF SOMEONE STEALS THE URINAL SCREENS AND SOAP DISPENSERS AGAIN, WE WILL SWITCH TO ONLINE SCHOOL!!"

Diabolical Touch 

A Touch so devilish, so cringy, so horrible it kinda works. It's a ball bouncing off a foot into no-mans-land but not so far that someone can steal it. The diabolical touch is seen mostly in JV soccer.

What a Diabolical Touch!
