Although it sounds strange to many people, arachibutyrophobia is a devastating fear for some people. The phobia is actually the fear of peanut butter sticking to the roof of one's mouth. The fear is often rooted in a more generalized phobia of choking or of sticky textures, but it can also occur alone.
Like all phobias, arachibutyrophobia varies in severity from sufferer to sufferer. Some people are able to consume small quantities of peanut butter, perhaps as a dip for vegetables, while others are afraid to try peanut butter at all. In some cases, the fear extends to other peanut products, from peanut butter ice cream to peanut sauces.
