A sometimes paralyzing mental disorder characterized by ongoing fear of chickens, both the birds themselves as well as any food made with chicken parts.
My supervisor walked into my office hungrily gnawing on a greasy chicken leg and then proceeded to ask if she could borrow my pen; I thought I would go entirely insane since it triggered my long-standing chicken phobia.
The fear of chewing gum. True thing, google it.
Not to be confused with the phobia that you'll open a packet of gum and have it taken by others, this is called high school.
Me: "Dude, I have got to become friends with Rebekah. She has chiclephobia, so she'll never ask me for my chewing gum!"
