This sound is tied to Valorant, Riot Games' tactical shooter released in 2020. Short UI and combat cues from the game are often clipped and reused in montages, TikToks and meme edits because players instantly recognize them. The one-kill audio stands out for being brief and satisfying, so it gets added to non-Valorant videos too whenever someone wants a clear success cue. Its continued use comes from how readable it is even in very short edits.
