Jengaphobia 

The inability to change programming code in a computer application for fear that the entire application will fall apart. Named after the Hasboro game "Jenga" where players had to remove pieces of a wooden stack until someone removed the piece that caused the stack to topple over.

Due to his jengaphobia, Bob decided to completely rewrite his computer application rather than modify the existing code.

Xenaphobia

The fear of being accosted by a large Amazon warrior-woman. Not to be confused with xenophobia, which is the fear that non-white people from a foreign country will waste use all the community resources before you get a chance to do so.

My xenaphobia kicked in when I attended the drag show and was accosted by a 6 foot tall woman dressed as 90s Madonna.

Junophobia 

A phobic disorder consisting of an irrational fear of teenagers who incorporate more than 10% of Urban Dictionary into their lexicon. Eponymously named after Diablo Cody's "Juno MacGuff" and the fear that some people have of teenagers that speak in that manner.

Person 1: Why are you avoiding her?
Person 2: Listen to the way she talks? She's too hip for me.
Person 1: The problem isn't her vocabulary, the problem is your junophobia.
