A person who has an extremely high capability of being a slut, while being stupid at the same time. Also known as a gufeyguber or anyone who goes by any variations of the name "Goo", "Gu", or "Gooey". Usually, a stupid slut also likes to wear mismatched socks and blue shoes, and a stupid slutty yellow baseball cap. They are also from the stupid slutty city of St. Louis, which is filled with stupid sluts, all of whom are inferior to he-who-may-not-be-named.
