The clip comes from a user-uploaded pet video that shows an iguana farting while sitting in a bathtub, which viewers can still find on YouTube by searching that exact phrase. Ripped as a short audio snippet, it spread through meme soundboards and prank compilations because animal bathroom humor travels well. It remains popular not for the reptile itself, but as a ready-made wet fart effect that feels funnier and less crude than a human recording, making it a safe gross-out gag for short edits.
