The Korean title combines the word for punch with peok, an onomatopoeia for a dull thudding hit, which explains the clip's short, blunt character. Sounds like this circulated on soundboards and in short form edits because a single clean punch sound can be reused for fights, pranks and exaggerated reactions without any dialogue. It stays popular for the same reason older cartoon hits do, it communicates impact in under two seconds and works even when the visual hit is intentionally fake or over the top.
