za warudo
A meme which was noticeably featured in this flash animation where Dio Brando and The World beat down a stickman, stopped time, threw knives, and crushed it with a steamroller with a cry of "WRYYYYYYYYYYYYYYYYYYYY".
The whole thing is based on the conclusion of the third story arc of JoJo no Kimyou na Bouken. It's also often associated with Izayoi Sakuya from Touhou due to her similar abilities.
Unless there is a specific reference to the "ZA WARUDO" meme, it is simply time stop.
