The glider is one of Fortnite's signature mechanics: after jumping from the Battle Bus, players deploy a canopy to steer their landing, a sequence every battle royale player has heard thousands of times since the mode launched in 2017. 'Gleiter' is simply the German word for glider, so this clip most likely comes from the German-speaking community's uploads. Like the Fortnite pump shotgun blast and the Fortnite default dance bass boosted clip, it has become shorthand audio for battle royale edits, drop montages and victory landings, and it still pops up wherever creators need an instant 'incoming' cue.
