B.F.W.O.C.
B. F. W. O. C. is when someone acts like they're your best friend, even though you've never agreed to it and they probably lied to get close to you. It’s like stealing your best friend spot without asking.
My ex tried to be my best friend again. I didn't ask for that. I didn't even like her that much.
My cousin says he's my best friend. He's not. He just wants my snacks.
My teacher called me her best friend. I didn't say yes. She's just trying to get extra credit.
