The person in a group of people (usually two, though sometimes more) who is most often left out of things.
The third wheel is usually there for one of two reasons - to act as a mediator, such as with a couple, or to be the "convenience friend" when nobody else is there to hang.
Third wheels are not normally forcefully excluded from activities, but they're not usually invited or informed about them either.
Not to be confused with being third-wheeled.
