The line comes from Barry, the HBO series about a hitman trying to become an actor, where NoHo Hank is the upbeat leader of the Chechen mob. His mix of warmth and criminal bluster made him a fan favourite, and short clips of his speeches are often lifted for memes and edits because his delivery turns a threat into a joke. The phrase works on its own without context, which is why creators reuse it to scold a group, open a fail video, or mock a bad idea.
