B.F.W.O.C.
B. F. W. O. C. is when someone tries to be your best friend without you knowing or caring. It’s like showing up uninvited to your best friend party and stealing the spotlight.
My neighbor said he's my best friend. I don't even know him. He just wants my Netflix password.
My friend's brother said he's my best friend. He's not. He just wants my lunch money.
My mom called me her best friend. I didn't say yes. She just wants me to do her chores.
