Similar to the Third
Wheel, the spare tire is that fifth person you bring on a double date who has to sit by themselves.
This can be especially embarrasing if the spare tire has to pull up a chair to a booth for four.
Spare tires are usually your socially
awkward homies or people you feel bad for.
I'm
never hanging out with Billy again. He said we were just going to the movies with 'some
friends' but I actually just got
played into being the spare tire!
