Garcello comes from Smoke Em Out Struggle, a popular Friday Night Funkin mod where the laid back smoker performs while constantly coughing between songs. That trait became one of his most recognisable features, so fans isolated his coughs for soundboards and meme edits. The long version spread through FNF clips, remixes and short videos where a prolonged wheeze works better than a short sound effect. It remains used because the cough is tied to a specific character rather than sounding like a generic stock recording.
