The line comes from Dragon Ball Z: Battle of Gods, released in 2013, during Bulma's birthday party on Earth. When the God of Destruction Beerus slaps Bulma, Vegeta, her husband, explodes in anger and shouts the line before attacking, briefly fighting with a power fueled purely by rage. Clips of the scene spread across anime edits, YouTube remixes, and meme pages, where the isolated shout became shorthand for overprotective anger. It remains popular because even people unfamiliar with Dragon Ball understand the reaction instantly.
