B.F.W.O.C.
B. F. W. O. C. is when someone acts like they're your best friend even though you didn't say yes. It’s like getting stuck with someone you don’t like in a group project.
My friend's little brother said he's my best friend. He's not. He just wants my video game console.
My boss said he's my best friend. He's not. He just wants me to work extra hours.
My pet said he's my best friend. I don't believe him. He just wants my treats.
