ZA WARUDO is a term used in JoJos Bizzare Adventure by DIO and Jotaro in which by saying this stops time for a few seconds.
DIO: So my The World's power and precision are both superior! I've seen enough. I'm satisfied.
I will end you now!
DIO: I have decided that I will show no mercy when fighting one of the Joestar bloodline,
but will kill them instantly!
*ora ora ora ora*
DIO: The way to end you is with The World's true power!
*ZA WARUDO! TOKI WO TOMARE!*
DIO: With this, the Joestar bloodline will finally end. My archenemies, who dared to make
an appearance in my destiny.. Farewell!
