Master Yi was one of the original champions released with League of Legends by Riot Games in 2009, built around Wuju style swordplay and high mobility. Every champion in the game has a distinct death sound, and Yi's short grunt became easy for players to recognise after thousands of matches. As clips and soundboards spread on YouTube and Discord, his death noise joined other iconic game death cues like the roblox oof in edits and memes, remaining popular because any League player instantly understands the defeat it signals.
