I can’t stop saying “yes yes yes!” every time I do some menial task around my apartment. I popped a single kernel of popcorn in my hair straightener. I’m eating a lot of ice cream, a dessert I don’t usually crave. I am fully Pinkydoll-pilled. And based on the dozens of people copying, parodying, or hating her after her style of streaming went massively viral in the last week, so is everyone else.

Pinkydoll is a content creator from Montreal who does "NPC" TikTok Live streams where she reacts to gifts from viewers, which appear as cartoon icons on the screen in real time: ice cream cones, roses, donuts, barbells, finger hearts. Each elicits a different, high-speed reaction from her. The gifts also have monetary value. Viewers purchase tokens from TikTok, which content creators can collect during streams and cash out in real currency. People on social media have dubbed this “NPC streaming,” after the non-playable characters seen in video games that react with rote, scripted phrases and robotic movements.
