FACB - FACB is when you're so annoyed you want to throw your shoes

FACB is when you're so annoyed you want to throw your shoes at someone.

My brother wouldn't stop talking. I said 'FACB' and threw my shoe at him.

My teacher gave me a pop quiz. I said 'FACB' and drew a face on my desk.

My friend called me late. I said 'FACB' and hung up on him.
