F.B.A.T.A
When Zach screams F. B. A. T. A at you he’s saying your butt is so bad it could ruin a birthday party
Zach: F. B. A. T. A! Your butt ruined my birthday!
Zach texts: F. B. A. T. A. Your butt is the reason my cake is sad.
Zach yells: F. B. A. T. A! Your butt is like a party crasher who brought a skunk!
