The name puk puk comes from the Russian imitation of a small fart sound, written as a repeated syllable for two short bursts. Clips with this title spread mainly through TikTok and short form reposts, where a simple, language free gag works across audiences without translation. Its popularity is tied to classic fart humor and to related clips like fart with reverb, which use the same joke in a bigger, more exaggerated way. Because the effect is short and clear, it keeps being reused for pranks, reaction edits and family friendly comedy.
