The exact origin of this clip is undocumented, as is common with short voice memes pulled from streams, vlogs, or group chats and reposted to soundboards. The phrase sino nagsabi nun is everyday Tagalog for who said that, and Filipino creators use it as a quick on-screen reaction to gossip, excuses, and bold claims in TikToks and short edits. It spread through meme pages and reaction compilations rather than a single viral video, and it sits alongside staples like bruh and the Emotional Damage meme as a compact way to demand a source.
