A friend that's last on your list of friends. A Fall Back Friend usually is the go-to
friend when none of your other friends are available. This type of friend usually is irritating and shows up at the worst times and says stupid things. this kind of friend hangs out with all of your other friends and ruins good conversations. Also, you don't know why you have his/her number on your phone since you would never call him/her. The fall back friend always asks to go with you to places when your going out with all your other friends

Fall Back Friend : "Can i come too??"
dude 1: "uhm, its kinda gonna be crowded."
fall back friend: "i don't care"
dude 1: *sigh* "ugh, alright, just don't bug us."

dude 1 : "no you're not."

The "friend" you go to when you have no one else to hang out with, whom you would never talk to otherwise.
Michelle: "Well, Kayla just ditched me and I don't want to stand here like an idiot. I guess I'll go talk to Janice, my fallback friend."
The friend that your other friends don't know, who you go to when the shit hits the fan.
Jack:I'm tired of all the drama,I'm gonna hang with Chris.
