The line is spoken by Thanos, played by Josh Brolin, in Marvel's Avengers: Infinity War from 2018, during a tense confrontation early in the film where his patience is clearly wearing thin. Clips of Thanos were widely shared after the film's release as his calm threats became shorthand for power online. This short warning was lifted onto soundboards and into short form edits because it works without context, letting creators turn an ordinary insult or boast into a moment that sounds like it is about to have serious consequences.
About this sound
Thanos saying you should choose your words more carefully from Avengers: Infinity War, used for warnings, threats and sarcastic replies in edits.
This is Josh Brolin as Thanos delivering a calm, measured warning: you should choose your words more carefully. There is no shouting or music, just a deep, steady voice that drops in pitch and menace with every word. The restraint is what makes it land. A character who could explode stays completely controlled, so the line feels like a final chance before consequences arrive. Viewers instantly read it as dominance and danger, which is why a three second clip works on its own without the scene around it.
