A person without a set group of friends or place to belong to. They drift aAround and meet new people, usually if dating someone. But if that relationship fails, they move onto the next lucky/unlucky clique. Floaters can either work alone or with a partner, but never exist as more than two people. Floaters are usually strange, creative, troubled, and/or have an offbeat sense of humor. Floaters usually don't mind being a floater, although bouts of loneliness may strike at times. A floater is usually single and plays the field.
After breaking up with her boyfriend, Ilona the floater found a new group of friends.
"What group of friends do you sit with?"
"Oh I only sit with my best friend. I'm a floater."
