A back-up friend - a friend you only talk to when your main squad is either bus

a friend you only talk to when your main squad is either busy, mad, or too high to communicate

They text you: 'Hey, I'm free!' You reply: 'Great! Let's go!' Then you realize you're the only one going to the mall.

They show up to the group chat and no one responds, but they still send 100 messages about how 'important' they are.

They’re the one who you call when your main friend is in the hospital, but then they take 3 hours to reply.
