The chill guy character was created by artist Philip Banks and first shared online in 2023, showing a relaxed dog-like figure in a sweater, jeans, and sneakers. It became widely known in late 2024 when TikTok users paired the image with captions about staying calm in stressful situations, turning it into shorthand for unbothered confidence. The Portuguese phrase translates the same idea, which helped the meme travel across Brazilian social media, where creators reused it for everyday moments that call for a deliberately relaxed response.
