Gambare means 'do your best' or 'go for it' in Japanese, and the cheer is aimed at Ryomen Sukuna, the King of Curses from Jujutsu Kaisen, the manga and anime series created by Gege Akutami. Fans took the short encouraging chant and turned it into a meme sound for edits, pairing it with clips of Sukuna fighting, smiling, or dominating his opponents. It spread through anime fan communities and short-form video platforms, where it became shorthand for cheering on a villain. Like Za Warudo, it works because the character is instantly recognisable and the moment feels larger than life.
