Boombye Boomba

From Philippine folklore, Boombye Boomba is a magic phrase that animates a wand for violent purposes:

"Oh, it is only a stick, but if I say 'Boombye, Boomba' it will beat you to death."

At the sound of the magic words the stick leaped from his hands and began beating his friend until he cried:

"Oh, stop it and I will give back everything that I stole from you."
