Flounder is one of the characters from the Disney movie "The Little Mermaid". He is a fish, and Ariel's best friend. So, if your name is Flounder you are a loyal friend.

An entrepreneurial bottom-feeding investor who helps build a (usually high-tech) company with the intent to sell it, usually at the expense of those who made it successful. The modern term for "founder." Named for a fish that evolved both eyes to the same side of its head, to facilitate bottom-feeding and hiding from predators.
