Back-up Friend

A friend who isn't really part of the group, but who you hang out with when the rest of the group is gone.

Why isn't Kailyn paying any attention to Meggie?

Oh, Meggie's just her back-up friend. She's talking to Ashley right now.

Backseat Best Friend

When your some ones best friend for a large amount of time, then after they lose all their good/best friends they cling to you. Then around 6+ months later when he/she gets their friends back, they start pushing you away slowly and moving towards their old friends again, but still call you their best friend.

Situation is made worse when said person is your Ex and you have feelings for them.

Bob: wow man did you see how Carly totally made Alex a Backseat Best friend? she completely ditched him.

Jake: Yeah man, really f'ed up

A back-up friend

A person that is a "friend" but is treated very poorly, and is only used as a second option incase their #1 friend isnt around.

back-up friends may be ignored, and not invited to things.
a back-up person are in a trio relationship of any kind

they may be that friend that walks behind the group when they are talking about something they didnt go to, and the friend that gets left on read in the groupchat and gets called annoying.

"I feel like a back-up friend when im around her." -1
"im sorry for you" -2
