The phrase comes from Tim and Eric Awesome Show, Great Job, the Adult Swim sketch series created by Tim Heidecker and Eric Wareheim that ran from 2007 to 2010. Great Job is part of the show title itself, reflecting its deliberately awkward, low budget public access style and enthusiastic praise for mediocre performances. Clips and catchphrases from the series circulated widely in early YouTube and meme culture, and this short praise line survived as a standalone reaction sound for edits, remixes and soundboards.
