The exact source behind the PBTV cackle is not widely documented, which has left listeners to describe it by how it sounds rather than where it came from, with one popular nickname calling it a submarine noise. That ambiguity has not stopped it circulating as a short reaction clip, where its brief length and instantly odd laugh make it easy to drop into memes, edits, and chat replies. Because it works without context or dialogue, creators keep returning to it for mocking moments, and its distinctive cackle helps it stand out among more generic laughter sounds.
About this sound
A short, high-pitched cackle from PBTV, often described as a submarine-like noise, used in reaction videos and memes to mock a silly or failed moment.
PBTV Cackle is a brief, manic burst of laughter that lasts just under seven seconds, rising in pitch and breaking into a sharp, almost mechanical cackle that some listeners compare to a submarine sonar noise. It starts quickly, builds with a wheezing, exaggerated giggle, and ends before it can settle, which makes it feel mischievous rather than warm. Played over a clip, it instantly frames the moment as ridiculous, mocking a bad decision, a failed stunt, or an awkward reveal without needing any words. The odd, echoing quality keeps it memorable, so viewers tend to replay it and recognise it even out of context.
