Grimace Shake

Origin

On June 12, 2023, McDonald’s launched the Grimace Birthday Meal to celebrate the birthday of Grimace, the round purple mascot the chain introduced back in 1971. A fuzzy blob of famously indeterminate species, Grimace had long faded into McDonaldland nostalgia, which made his sudden 2023 revival all the more surreal. The birthday promotion bundled a main item and fries with a limited-edition, berry-flavored purple shake. Within roughly a day, TikTok creator Austin Frazier (@thefrazmaz) posted the video that started everything: he cheerfully wished Grimace a happy birthday, sipped the shake, and then hard-cut to himself slumped over and motionless, purple goo smeared everywhere, as if the drink had killed him. The clip reportedly pulled in millions of views, and a rigid new format was born almost overnight.

What it means and how it is used

The joke splices a wholesome fast-food promotion with the grammar of horror movies, found-footage and creepypasta. The template is simple and repeatable: film an upbeat, smiling toast to Grimace, take a drink of the purple shake, then smash-cut to a fake ‘aftermath’ in which you are collapsed, bleeding purple, possessed or dead while ominous music plays. The humor comes from the whiplash between a friendly mascot birthday and a bloodless, obviously absurd crime scene. It quickly generalized into a blueprint for any ‘cute thing with a sinister twist’ gag.

How it spread

The trend exploded across TikTok through June and July 2023. By mid-July the #GrimaceShake hashtag had amassed well over 145,000 posts and more than a billion views. Crucially, McDonald’s declined to shut it down and instead leaned in: on June 27, 2023, the brand’s account tweeted in Grimace’s own voice, joking that it was ‘pretending’ not to see the trend, a post that racked up tens of thousands of likes. The company’s head of social media later admitted the team had been genuinely surprised by the whole phenomenon. Major outlets including CBS News, TODAY and NBC News ran explainers on the ‘unhinged’ trend, and creators far larger than Frazier piled in, each racing to out-do the last cut-to-chaos punchline.

Notable examples and variations

• Thousands of ‘took a sip, then…’ cut-to-chaos videos throughout summer 2023.
• Elaborate purple-splattered ‘scene’ recreations set to eerie or dramatic music.
• Brands and creators parodying the format with their own products and mascots.
• Kid-friendly channels doing tamer ‘the shake is back’ spins on the bit.

Legacy

The Grimace Shake became a textbook case of accidental marketing: a slightly unsettling, fan-made horror joke that drove real people to buy the actual product and boosted McDonald’s sales among younger customers. Because the ‘gore’ was cartoonish and clearly fake, the trend stayed broadly brand-safe even as it went viral, and McDonald’s low-key participation only amplified it. The purple shake was a limited-time item and soon vanished from menus, but the format outlived it and Grimace enjoyed a genuine cultural resurgence off the back of it. Around the same launch window, Grimace threw a ceremonial first pitch at a New York Mets home game on June 12, 2023; when the team caught fire afterward, fans adopted him as a good-luck charm, handing the character a second viral life entirely separate from the horror trend.
