The phrase comes from German internet slang, where ultra geil is an emphatic way to say something is extremely good, and gefolgt simply means followed. Online, the clip circulates as a short meme reaction detached from any single source, shared on soundboards and reused in stream edits and short videos. Its popularity comes from that everyday streaming context, because follows and joins happen constantly, giving creators a ready made exaggerated response that can be dropped in again and again without needing extra explanation or setup for the audience watching.
