Crazy Diamond is the Stand of Josuke Higashikata, the hero of Diamond Is Unbreakable, the fourth part of JoJo's Bizarre Adventure, which first aired in 2016. The summon sound marks the instant the pink-and-blue Stand materialises to heal or strike, and fans quickly clipped it for edits, memes and reaction videos. Like Za Warudo and the To Be Continued meme, it became shorthand for JoJo style drama, and it is still used because that one-second burst instantly tells viewers a powerful Stand is entering the scene.
