The origin of Abrluabrlua is not documented, and the title itself appears to be the sound written out as gibberish rather than a quote from a known show. Clips like this spread on soundboards because the name matches what you hear, making it easy to search for and share. Its short length and loopable babble have kept it in rotation for reaction edits, gaming montages and meme compilations where a character needs to sound overwhelmed, tongue-tied or completely lost for words in under two seconds.
