Fall Back Friend

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
dude 1 : "Hey guys, we're chillen at mike's after school! john's bringing the drinks and steve's bringin the food"
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."
fall back friend: "Gee, Thats swell! I can't wait! I'll Bring my entire deck of pokemon cards and we can play all night!"
dude 1 : "no you're not."
