Great Success is the signature catchphrase of Borat Sagdiyev, the fictional Kazakh journalist played by Sacha Baron Cohen. The character first appeared on Da Ali G Show before headlining the 2006 mockumentary Borat, where the line punctuates his clueless triumphs. Clipped into a fraction of a second, the quote became a staple reaction on YouTube compilations, soundboards and TikTok, usually played over ironic or exaggerated wins. Its staying power comes from instant recognition: even viewers who never saw the film know the accent, the timing and the joke.
