The phrase is Finnish slang built around the name Hessu, a familiar Finnish first name also used for a well known cartoon character locally. The recording itself comes from an online voice changer tool, as credited in its audio file tags, rather than from a film, show or song. Short voice changer clips like this spread on soundboards because they are easy to spam, quote and drop into chats without context. Its appeal stays mostly with Finnish speaking audiences who catch the rude meaning immediately, while the processed voice makes it shareable even as a nonsense sound.
