The sound comes from Lily Bell, a Spanish-speaking VTuber known online as LilyBellVT and LilyBell Ch, whose streams feature character voices and exaggerated reactions. Clips of her screaming in her mañosa persona were cut and shared by fans as short reaction audios on soundboards and in fan edits. The phrase grita en mañosa describes that specific playful scream, which is why fans search for it by that name. It remains popular in small VTuber communities for memes, alerts, and comedic edits.
