Bootsaphobia 

When a male or female is afraid of losing their significant other to a mustached male oozing machismo who wears big boots as a fashion statement

"Is Carl coming to Jesstlemania?"
"No, he has Bootsaphobia and decided to stay home with his wife"

A fear that a boomerang is going to come back and hit you

I threw a boomerang once, now I have boomaphobia.
