expendable friend

That friend thats around when you need them but not when you want them. Close to second hand friend but an expendable friend is constantly treated like they dont matter, regardless of how far they go for another. An expendable friend can be replaced very easily. Despite being told their important.

"Man, they(he/she) always third wheels those two, what an expendable friend"

Expandable friend 

The friend who is always left behind. Never gets invited to things ,and is often lonely . Also someone who is always being there for someone but have no one in return

I feel bad for her she's such an expandable friend to everyone
