Gum (superstition)

In Turkey and Hungary, it is considered bad luck to chew gum at night during a special occasion, such as a big date, because, according to superstition, chewing gum meant that you would actually be chewing on human flesh. Because of this superstition, it's generally recommended that you shouldn't chew gum while on an important date, and that you should stick to mouthwash instead. This superstition was brought up by the author Harry Oliver in his book, "Black Cats and Four Leaf Clovers."
