Towlie first appeared in the South Park episode Towelie in 2001, created by Trey Parker and Matt Stone and voiced by Vernon Chatman as a genetically engineered talking towel who is almost always high. The character became a recurring fan favourite for lines about bringing a towel and having no idea what is going on. Short voice clips of Towlie later circulated on soundboards and in meme edits, where this brief acapella hum is reused whenever a scene needs an unmistakably spaced out reaction.
