This audio is mainly known online by the label “Peru” and the repeated “glugluglu” sound rather than by a clearly documented source clip. It spread through short meme edits, reposts and chat-share audio culture, where tiny, strange sounds often become in-jokes because they are easy to drop into almost any format. Its staying power comes from how short and flexible it is: the sound can tag confusion, nonsense, awkwardness or pure randomness in just a few seconds.
