Big Belly Boy 2 circulated as a user uploaded soundboard clip under the name olszakumpel, with no clear original film, show or song credited in its listing. That loose origin is typical for meme audio, where a short joke gets ripped, renamed and reposted until the title itself becomes the search term. The number 2 suggests a follow up take on an earlier Big Belly Boy clip, giving regular users a second version to choose from. It stays in rotation because the belly gag is visual, universal and easy to remix into new edits.
