mysterial 

A mysterial is a mystery brake pad material of unknown quality, origin, performance, degradation or composition offered by a brake pad manufacturer for which no fucks are given as they should be focusing on a reliable supply of their popular core product offering.

Today I received a phone call from a manufacturer offering a new mysterial when I can't even get a supply of the popular materials.

Coitus Mysterioso 

Drunken sexual encounter where coitus may or may not have occurred.

Charlie thinks he had sex with this girl a few weeks ago, and she was begging for it, but he's never had sex with her before, or after, so for now it's classified as a case of coitus mysterioso.
