This clip is associated with Team America: World Police, the 2004 satirical puppet film from Trey Parker and Matt Stone. The song phrase became a long-running internet meme because it is instantly recognizable and easy to use as a punchline for exaggerated patriotism, overblown action, or mock-national pride. Even short trims of the chant still work well in edits, reaction videos, and meme compilations because the joke lands almost immediately without needing much setup.
