The 'I Regret Nothing' catchphrase is a staple of internet culture, often used to express defiance after doing something absurd, shameful, or chaotic. While the phrase has roots in various media, it gained significant traction through the video game Postal 2, where the protagonist screams the line as a signature quote. Over time, it evolved into a popular reaction image, frequently featuring animals (like cats stuck in strange objects) or characters in ridiculous situations who refuse to admit defeat. It perfectly captures the spirit of leaning into one's mistakes with humor and unearned confidence.
