Unlike a line from a film or show, this is a everyday foley-style sound effect rather than a clip tied to one character or release. Can opening sounds have long been used in advertising, cooking videos and comedy sketches to suggest a cold drink instantly, and the same short pop and fizz has become a staple of online editing. Creators reuse it because it is instantly recognisable, needs no explanation and works in seconds, whether for a thirst joke, a celebration or a satisfying ASMR moment.
