It's like a schematic of 3 wheels about the moment socialization:

-Third Wheel: biggest one, which consist in a group of people whom are you fond of, but not being very intimate.

-Second Wheel: small and inside the Third Wheel. People that is priority of your attention.

-First Wheel: smaller and inside the Second Wheel. Consists in something/yourself (or both) that is automatically a main concern.
Usually, for the majority of these wheels are like this:

-Situation: going out with friends/family and bf(gf).

Third Wheel: your friends/family

Second Wheel: your bf(gf)

First Wheel: yourself/your beliefs/your pride/your ego

-Situation: going out with friends.

Third Wheel: most of your friends

Second Wheel: your best friend

First Wheel: yourself/your beliefs/your pride/your ego

One who deters the socialization of a couple, perhaps when being invited out of pitty or through a feeling of duty. This person may be eased into the situation by being allowed to stay in an envirnment he or she has become accustomed to (perhaps a kitchen, where the third wheel can bake cookies for the couple.) The third wheel may feel uncomfortable about watching the couple canoodle on his her her sofa, but none of this is taken into consideration.

A person hanging out with two people (usually a couple) that are in a sence leaving him/her out. Called the third wheel because either:

-Having any odd number of wheels on an object generally messes it up.

-Third wheel on a bike makes a tricycle, something thats safe for kids be left alone with.

Where one person hangs out with two people who are dating in situations and places where couples usually hang out like at the movies or at restaurants.

Third wheelers make the situation extremely awkward for a couple to show affection towards each other or talk about things pertaining to their relationship.

Third wheelers also invade time with potential couples. Usually they are invited to hang out because of pity and consideration. It is also awkward for the one who unintentionally becomes the third wheel when the couple sort of distances themselves from them so that they can do things as a couple.
I'm not going to the movies with you guys tonight, I don't want to be a third wheel. It is like watching a poorly scripted romance movie!
