The Grimace Shake is a berry-flavored milkshake that was first sold at McDonald's restaurants in the United States, from June 12, 2023, to July 9, 2023, to celebrate the 52nd birthday of Grimace, the purple monster mascot from McDonaldland. The shake was later also introduced as a time-limited item in Australia, Canada, Ireland, Japan, New Zealand, the United Kingdom, Brazil, Hong Kong, Turkey, Ukraine, Moldova, Croatia, Germany, Israel, Mexico, Venezuela and Singapore.
The shake gained popularity on TikTok, YouTube and Instagram with the #GrimaceShake trend, where users filmed themselves drinking the shake and then finding themselves in ominous and gruesome staged situations.
