Amumu is the Sad Mummy, a champion in Riot Games' League of Legends, known for his lonely, melancholic personality and soft, downcast voice lines. Short clips of his sighs and groans have circulated on gaming soundboards and meme pages, where players recognise the tone even without seeing the character. Because the sound lasts only a little over a second, it works as a quick reaction rather than a full quote, and it has stayed popular with League of Legends fans and video editors who want a gentle, readable cue for disappointment, bad luck or a plan falling apart.
