A fun one for you now and everyone knows the JoJo reference "Za Warudo" but this massive memeable phrase didn't originate from JoJo.

Satorius or Takuma Saio is a major antagonist from Yu-Gi-Oh GX in the Society of Light arc looking way less deranged in the picture but I assure you that he sported some trademark psychotic eyes as so shows in Yu-Gi-Oh villains.
A brief description of his deck showcases cards inspired by Tarot Cards, Saio being a fortune teller himself, so a tarot deck suits him.
If you know your tarot cards, one of the cards is called "The World" which he plays against Judai.
Now Saio here is voiced by Dio Brando voice actor Takehito Koyasu and he does indeed utter the words "Za Warudo" predating his appearance as Dio Brando by quite a margin, meaning that Za Warudo is a Yu-Gi-Oh reference not a JoJo reference.
If you want to be technical, it's a trademark of Takehito Koyasu's acting.
So a nice little fun fact for you.
