The phrase survey says comes from television game shows, most famously Family Feud, where it introduces the answers ranked by a studio survey. Online, creators borrowed both the phrase and the accompanying correct answer ding and turned them into a reusable meme cue. Short clips like this one spread through soundboards and video edits because the sound is instantly understood without any context. It is now used far beyond quiz content, as a shorthand for approval, validation and getting something exactly right in everyday situations.
