The line comes from the opening cutscene of Link: The Faces of Evil, one of the Philips CD-i Zelda games released in 1993, where Link complains to Zelda about the lack of action. The games became notorious for their cheap animated cutscenes and odd voice acting, and clips were heavily remixed in early YouTube Poop videos in the mid 2000s. That second life turned many lines into reaction sounds, and this complaint survived because it fits any dull, slow or empty moment in games and streams.
