The 'Oh No Baby! What Is You Doin???' meme originated from a viral video posted by Nick Cassano, better known as NickNack PattyWack, in late 2017. In the video, Cassano films a woman in a parking lot who appears to be struggling with a confusing situation, prompting his iconic, high-pitched comedic commentary. The phrase quickly became a universal internet reaction for witnessing someone commit a social faux pas, a massive fail, or an obviously poor decision. It is widely used across social media platforms like Twitter and TikTok to express a mix of disbelief and humorous disappointment when common sense seems to have been completely abandoned.
