The Borat meme stems from the 2006 mockumentary film 'Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan,' starring Sacha Baron Cohen. The character Borat Sagdiyev became an instant internet sensation due to his broken English and absurd catchphrases like 'Very Nice!' and 'Great Success!' These expressions are typically used as reaction images to mock sincerity or celebrate ironic victories. The memes often capture Borat’s exaggerated facial expressions, making them perfect for satirizing social situations and displaying over-the-top enthusiasm.
