A fear of Benji Knoll, a creepy-ass character in the "Queen B" series (App: Choices). His crimes include stalking, harassment and theft. He literally stole the main character's bra, perfume, etc, and he made a SHRINE. This dude is mentally ill.
Sabrina: Oh my god, I just read chapter 9 today, that shrine was so creepy, I think I have benjiphobia.
Amber: I don't even read "Queen B" but after seeing the shrine screenshots, even I have benjiphobia now.
The fear of knees, specifically the fear of seeing uncovered knees in person, or even on film. People with this phobia may be afraid of all knees, only there own, or only others.
P1: Dude! Get your wrinkly old knees away from me they’re freaking me out man!
P2: Ha! Seriously man? Your afraid of my knees?
P1: Yeah man! It’s an actually condition called genuphobia, which I have! Now will you put on some longer shorts?
