The phrase comes from clips linked to Tri Kota, known in English as Three Cats or Kid-E-Cats, a Russian animated series about three kitten siblings. Short voice lines from children's cartoons became a steady source of TikTok reaction audio because their clear, exaggerated delivery is easy to lift out of context. This fragment spread as users reused the unfinished sounding 'poshel na' line over unrelated footage, turning a throwaway cartoon moment into a general shorthand for leaving, refusing, or sending someone off in Russian language edits.
