Little is documented about where the chu tai sen la chant was first recorded, and it appears to have surfaced as an anonymous upload on user generated meme soundboards. Like many goofy ahh sounds, it spread through short edits and reaction clips where the humor comes from the chant itself rather than any known character or show. Its staying power is its rhythm: the four punchy syllables work as a quick taunt, a celebratory shout, or a nonsense button between jokes.
