The name comes from Korean internet slang, where haemjji is a cute way of saying hamster and chok mimics a small moist smack. No single film, show or creator is credited with the clip, so its life is mainly online as a shared soundboard effect. Its brevity helped it spread in short form edits, where creators need a reaction that finishes before the next cut. It remains popular for pet content because the tiny pop matches hamsters and other small animals without overwhelming the scene with a bigger cartoon effect.
