When McDonald’s recently rolled out its Grimace Birthday meal, it probably didn’t expect it would spark a trend of Gen Zers pretending to pass out or be attacked by the purple blob. But that is what is happening on TikTok, where the “Grimace Shake trend” is the latest brand-inspired social media trend to take hold.

The TikToks start with someone (often a teenager) wishing Grimace a happy birthday and taking a sip of the shake. The video quickly cuts to the person passed out on the ground or against the wall with their face and chest covered in the milkshake. Some cough and sputter up the drink. Many of the videos are like mini horror films, shot in the dark on playgrounds or parking lots, or in cars. On TikTok the hashtag #grimaceshake has 370 million views at the time of writing.
