Third Wheel

What does third wheel mean?

A person who feels left out

Third wheel is a term for the feeling a person experiences when he or she feels left out. It commonly occurs when a person is hanging out with two other people who are acting more intimate and romantic.

Since wheels usually come in twos or fours, like with bikes and cars, a third wheel seems odd, which plays into the "odd one out" feeling. Third wheel situations may arise for a variety of reasons such as the couple feels bad for a friend and invites him along or the third wheel is socially unaware of the situation and when to leave the two people alone.


Ugh, last night was the worst. I felt like a third wheel all night long
Well, yeah, you did go out with them on Valentine's Day
See if you can guess the third wheel
