The clip comes from a fan-made voice sample recorded in Audacity by its creator, kalbright3275, using Cosmo G. Cellsley, an original character associated with the Amoeba Sisters community and the fictional Cellsley Sprockets, with casting credited since 1992. Shared as a short reaction sound, it circulated through soundboard and meme pages where users searched for an over-the-top firing line. It remains in use because the line is short, instantly understood, and easy to drop into pranks, gaming clips, and comedy edits.

Cosmo G. Cellsley shouts get outta here, you're fired in this voice clip from an Amoeba Sisters original character, used for prank reactions and meme edits.
This is a loud, theatrical voice clip in which Cosmo G. Cellsley, an original character created for the Amoeba Sisters universe, loses his temper and barks out a dismissal. His voice rises sharply, the words come out fast and forceful, and the delivery sounds like a boss who has finally run out of patience. The shouting is clear and exaggerated rather than realistic, which makes it instantly funny when it lands over a video. It works as a punchline because the anger feels over the top, turning an ordinary rejection, failure, or unwanted guest into a dramatic, memorable moment for viewers.
