Similar to the popular M.O.A.B. in Call of Duty, the S.O.A.B is the son of all bitches. This is often used when wishing to address someone who is hated throughout your school or workplace. Can also be used when shouting out to one of your friends.
"You S.O.A.B. I will murder you like you recently murdered my family!" or "Stacy you crazy S.O.A.B. Get over here you slut :D"
