初六送我自己

Meaning

"Hǔ huǒ fā dòng" (虎火发动/Tiger Fire Launch) was originally short for "Triple MIX," a call performed during idol live performances. Named after shouting "tiger, fire" in English, Japanese, and Ainu. Later at a Zhong Yingtao performance, a fan shouted "虎火发动" in Chinese instead of foreign languages, becoming a joke. It was then imitated as a meme and became trendy. As a MIX word, it has no actual meaning—just a chant matching idol music rhythms. Outside concerts, it's used for hype.
