Yawnophobia

The fear of seeing someone yawn in public, causing you to yawn, thus creating a chain reaction in your group of friends until they beat the living $*#! out of you for starting it.

Steve: "Dinner tonight? The usual spot."

Jimmy: " No man, I'd love to come to Quiznos, but I have serious Yawnophobia after what happened."

Steve: "Shit man, you should stay home, I'll kill you if you start that crap again like you did last week."

The Yawning Abyss 

The Yawning Abyss is a ride from the Theme Park Sans World, created by the youtuber CallMeCarson and his friends, this ride makes you question your spatial perception of the universe.
Once you come out you'll be ascended, you won't even need to comunicate with language, you'll be able to comunicate telepathically.

It is said that if you gaze into the Yawning Abyss for long enough you may just return with an inkling of the Merciless SunGod's vast knowledge.
