The clip circulates on user soundboards under the short name Pim, with its file title in Finnish reading Antti vain nauroi, meaning Antti just laughed. That pairing explains how it is used online, as a named laugh reaction rather than a song or dialogue line. Short laugh and blip sounds like this spread because they are easy to trigger mid conversation, fit almost any embarrassing or silly moment, and need no context to understand. It remains popular as a compact reaction button for chats, streams and edits.
