The phrase comes from everyday Brazilian Portuguese, where being on the floor is a vivid way to describe feeling floored by something unexpected. Online, the short recording circulates as a reaction sound in meme edits, gaming clips and group chat shares, especially for falls, defeats and moments of secondhand embarrassment. Its popularity comes from its brevity and clear physical image, which translates easily even for viewers who do not speak Portuguese and still understand that someone has been completely overwhelmed by what just happened in the scene.
