The word ‘arachibutyrophobia’ is derived from arachis, meaning ‘peanuts’. The full meaning of the word is fear of peanut oil sticking to the roof of the mouth. Arachis is a kind of oil found in many nuts and peanuts which stick to the roof of the mouth. In many cases, the saliva fails to dissolve this. A person is not able to extract the sticky thing, and thus faces embarrassment, especially in public places, and develops a fear of it.
