The phrase comes from Russian internet slang, where pofigu is a blunt way of saying someone does not care at all. The clip is associated with streamer Red21, whose version helped it circulate as a short reaction sound in Russian-speaking gaming and meme communities. From there it spread through short videos, streams and soundboards, where creators reuse it as a quick comeback rather than a full argument. Its staying power comes from its simplicity: the meaning is clear from tone alone, and the line fits almost any moment when indifference is funnier than a reply.
