Jeffy was created by Logan Thirtyacre for the YouTube puppet series SuperMarioLogan, later rebranded as SML, and debuted in 2016 as a dim, loud mouthed adopted son in the main cast. Clips of his voice and bodily humor were quickly cut into soundboards and short meme edits. This farting version spread in the same way as other toilet humor staples like fart with reverb, shared for pranks, remixes, and reaction videos where a long, unapologetic fart is funnier than a short one.
