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

Back-up-break

When someone stops at a red light next to an old person, slowly starts backing up, and yells "put on your brakes!" at them.

I can't wait for the day I get to back-up-break some unsuspecting old fart!
