Filler Friend 

A filler friend is the one who is always walking behind the group when there's no room left or will often times be forgotten to be invited to events or gatherings. Usually ends up the designated driver when actually invited.

Jeff: "Hey man, that movie was badass!"
Eric: "Yeah dude, it was awesome!"
Tyler: "Oh.. you guys went to the movies last night?.." I'm so tired of being a filler friend..
