This clip is best understood as a generic television-style audience cheer rather than a quote tied to one famous speaker. Sounds like this became popular online because they instantly mimic the feel of daytime TV, late-night interviews, and game show reactions. Creators use them to exaggerate approval, make simple moments feel absurdly successful, or parody the rhythm of studio entertainment. Its staying power comes from how fast listeners recognize the format: one short burst of applause can completely change the tone of a scene.
