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.

hystericalyrical 

When someone sings a song and does not know the proper lyrics of the original and ad-libs their own lyrics. They usually think the incorrect lyrics they are singing are truly the words of the song.

Todd: "Last nite, Valerie was singing karaoke to Men at Work's "It's Summers Day""
Brent: "Yeah, she kept singing "It's a Mistake, It's a Misssstake. Instead of "It's Summers Day""
Todd: "Dude, that was hystericalyrical!!"
Brent: "Yeah, like when I rambled through Barenaked Ladies "One Week" lyrics!!!!"

Mysterically 

Mysterically is a word that has yet to be defined by the english dictionary but is used in many culture's vocabulary to include: Germany, France, Pakistan, Iraq, and even Iran. It is meant to show that something has happened that there is no real reasoning for.

My backpacks mysterically disappear from my room when my friends are there.

Mysterical 

When you're not sure if a situation merits reverent awe, or pee-your-pants laughter.

We experienced a mysterical moment when, gathering on the dry lake-bed playa at sunrise to meditate upon the birth of a new day, our solemn reverie was interrupted by an enormous, motorized pink hedgehog, backfiring and farting across the horizon.
