Arachibutyrophobia: The fear of peanut butter sticking to the roof of your mouth.
It’s an uncomfortable feeling for everyone, but the fear of peanut butter sticking to the roof of the mouth is a full-blown phobia for some. Some people can handle eating small amounts, but others avoid peanut-based products like peanut butter sauces and ice creams. It can be rooted in a broader phobia like the fear of sticky textures or choking, or it can occur independently.
