it is bigger than a boo yaa, which is slang for a 12 gauge detonation. this is like both barrels or say a piano falls on yer head or say a large rifle caliber goes off (.50 bmg or .700 action express) and shoots a cashier at stop n go and rips him in half. if a boo yaa its usually boo yaa boo yaa but boo-yaka-shaw is only used once.
you got a 12 gauge loaded with slugs and this punk starts talkin wak and every time you shoot him you tear off a shoulder and arm or blow offa leg. thats boo-yaka-shaw
