Ol' Five-Wheels

The chronically lonely man. Ol' Five-Wheels is the name given to anybody that goes out regularly with one or more couples and no partner of his/her own, always forced to sit in awkwardness as the couples get all lovey-dovey over each other and act as if s/he doesn't exist. Who knows why s/he does it- perhaps they continually hope that one day, somebody will take notice, or perhaps they have no other friends. Whatever the reason, the name is theirs, and evermore shall be (until they get a partner of their own and do the same thing to somebody else).
