As I recently learned from Mental Floss, “arachibutyrophobia” is a word. According to dictionary.com it is:

noun
a fear of peanut butter sticking to the roof of one’s mouth

Is this really a condition? Even if it is, does it need a specific word to describe it? This is a general problem: most phobias don’t deserve to have a term defined for them. I understand having words for the fear of heights or fear of spiders. Those are natural, evolutionary survival responses. But do we need a word for the fear of flutes (aulophobia)? Or the fear of sitting down (kathisophobia)? Defining terms for these conditions removes their irrationality. Someone who is afraid of flutes does not need validation; the person needs help, or at least the shaming that comes from saying the words, “I am afraid of flutes.”

Check out this list of phobias for hundreds of other words we don’t need. Except for scabiophobia. Let’s keep that one.
