The phrase in the title is a playful Russian spelling of an English oh my god exclamation, written as it sounds rather than as standard English. Clips like this circulate on user generated soundboards where short reaction voices are saved, replayed and remixed into new videos. Its spaced letter ending adds to the joke, making the moment feel stretched out and absurd. It has stayed in use because shocked exclamations fit almost any context, from gaming and pranks to everyday chat reactions, without needing any setup or explanation.
