This sound is tied to El Risitas, the Spanish comedian Juan Joya Borja, whose laughing TV appearances became a huge meme source online. In French internet culture, “Issou” became especially associated with forum humor and remix edits during the 2010s, where the clipped vocal outburst was reused as a recognizable in-joke. It stayed popular because it is short, instantly identifiable to many French-speaking users, and easy to drop into ironic reactions, low-effort edits and chaotic meme compilations.
