Ff Is short for forbidden friends. It's when friend 1 & friend 2 wants to be biffles but their separate group of friends are like da fuq. like really. I can have play dates with anyone I want

Friend 1 : lets have a play date.

Friend 2: omg yes!

friend 1's group: dude why are you with friend 2, it's not that I don't like him/her, it's just wierd.

Friend 1: but she's like my biffle.
Friend 1's group: we're your biffles ugh. when did you start to ditch us.

friend 2's group: why are you suddenly hanging out with friend 1?
friend 2: you don't like her/him?
friend 2's group: we do but like it's weird. You're supposed to be with us.

like honestly. You need to stop and let friend 1 & 2 have other friends besides forcing them to hang out with your group.
