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.

Juggaphobia 

The psychological fear or extreme hatred of juggalos and what they stand for.

Jake: I fucking hate juggalos. I hope they all die painful deaths. If there was another holocaust, except juggs instead of jews, I would become a nazi.
Mark: Whoa, dude, you've got a serious case of juggaphobia, you should consider counseling.
