Sheetnado 

When a significant other generates a tiny vortex from restless body spinning during a deep sleep cycle that sucks all existing bed sheets in the area toward his/her core creating a burrito-like sheet structure and no sheets for any other occupants in the bed.

I woke up with no sheets again this morning... The Sheetnado strikes again!

Shartnado

An explosive unintended defecation that occurs when one relaxes the anal sphincter to fart, with a twist.

After my fifth bean burrito, and three cups of coffee, my bunghole released an EF5 Shartnado that leveled my pants.

shartnado

A defense mechanism, not unlike a squid releasing ink, wherein the cornered prey releases a flurry of flatulence and feces in a panicked attempt to distract, confuse, and evade an unrelenting predatory attack.

Wow, Spicy’s press conference is fubared, and they’ve already used up the alternative fact defense, so what’s he gonna do?
Only one card left to play man… the Shartnado. Stand back.
