Like third wheeling a couple but so much worse because they're not actually in a relationship. You find yourself drifting apart from your best friend as they get a new bff even though they pretend you are still friends and try to keep up the pretence by inviting you with them sometimes. But even when you are with them you feel like they would be happier without you there. You wish your old bff friend would notice how you feel and you would become as good friends as you were before but inside you know that will never happen.
*you, your old bff friend and their new bff are walking together. There talking about plans for next weekend and what they did last weekend; neither of which you were are invited to* I feel like a friend third wheel right now.

Somebody that is always a third wheel because he or she has nothing else better to do, or has no friends to do anything with.
Me:I was hanging out with my girlfriend all day, and Andrew just tagged along everything we did.

Friend:Man what a third wheel tyler!!!

A test to see if a guy and a girl are more than just friends. You hang out with them, and if you feel like a third wheel, there is something more going on.
-"Are John and Ashley dating?"
-"They claim to be 'just friends,' but I ran the third wheel test and it came out positive"

Get the The Third Wheel Test mug.
When a couple becomes bored with their relationship and begins to constantly "hang out" with a "friend" together and thinks this friend is the coolest thing ever. Both people in the relationship crush on the friend, usually unknowingly at first. A third wheel crush requires at least one bi or gay person on the couple's side.

As Kit Porter from the L Word says, it's dangerous business.

If you identify yourself as the third wheel crush in a friendship, get out of it fast. It usually leads to one of them cheating with you, a threesome that goes nowhere, or lots and lots of screaming and blaming you for destroying what they had.
Friend #1: "John and Mary text me every day asking if I want to go over to their house and hang out. And then each of them will invite me to go eat out without the other being there, like they're taking me on a date. If they weren't together I'd think they both had a thing for me."

Friend #2: "You're in the middle of a third wheel crush, man. Nothing good can come from this."
