The sound takes its name from Cristóbal Soria, a Spanish football pundit whose expressive television presence has made him a familiar figure in online football humour. Short clips featuring his reactions are widely shared by fans, and a whistle works especially well in that world because it instantly reads as teasing, disapproval, or celebration without translation. On soundboards and in short-form edits, it has become a handy shorthand for a moment that is too funny, too awkward, or too unbelievable to leave uncommented.
