The phrase taste the rainbow is widely known as a long running candy slogan, and online creators repurposed it as an aggressive meme line by shouting it out of context. This shortened version spread on soundboards and in short form edits because the contrast between a cheerful slogan and an angry delivery is instantly funny. It is now used less as a reference to the advert and more as a standalone meme sound for sudden attacks, colorful chaos, and exaggerated confrontations in fan edits.
