The line comes from Marvel's Black Panther, where it is used to shut down behaviour that does not belong in Wakanda. Clipped from the film, it spread through meme pages and short-form video as a reaction sound for calling out rule-breaking, bad manners, and out-of-place ideas. Its appeal has lasted because the delivery is calm rather than angry, making it work for light jokes as well as sharper social commentary, and because almost any audience recognises the moment instantly.

The Black Panther line We don't do that here is often used as a firm dismissal in memes when someone breaks a rule or does something unwelcome.
The clip is a short, deadpan spoken line delivered with calm authority, each word landing firmly rather than shouted. Its dry, almost bored confidence makes the rejection feel final, as if the speaker is stating an obvious rule instead of arguing about it. That understatement is what gives it its comic punch: the listener instantly understands that whatever just happened is not welcome, not normal, and not up for debate. In a video, it works like a verbal door closing, cutting off a bad idea, an awkward attempt, or an outsider who has misunderstood the room.
