Get the Third wheel mug.
When you are hanging out with two other people usually friends, siblings, or relatives. They always talk to each other and have fun, but you are just tagging along and overhearing what they say. They act like you are not there. Sometimes you have no one else to hang out with so you just go with them. You will always feel left out.

A person who hangs out with two other people. The two other people are closer to each other than the "Third Wheel". People generally feel awkward when the third wheel mentions how much it sucks to be the first wheel (They actually normally get mad).
