This audio appears to be a very short text-to-speech rendering tied to Fortnite rather than a longer in-game quote or cinematic line. Fortnite, released by Epic Games in 2017, became one of the most referenced games in meme culture, so even a single spoken mention of its name can work as a joke online. Clips like this stay useful because they are brief, instantly recognizable to gaming audiences, and easy to drop into montages, reaction edits, and parody posts.
