The exact origin of this clip is unclear, but it circulates on German meme soundboards and in messaging groups as a go-to hype reaction. Shouting 'ultrageil' about a pineapple turns a random fruit into a symbol of something being the absolute best, which is exactly why the joke works. Like the oh my god, wow reaction, it thrives on exaggerated enthusiasm, and creators keep reaching for it because the phrase is short, loud and instantly funny even to people who only half understand the German.
