Pilk, a portmanteau of Pepsi and Milk, became a viral internet sensation as a 'cursed' beverage choice before evolving into a legitimate pop culture moment. While the concept of mixing soda and milk has existed for decades under various names like 'dirty soda,' the specific term 'Pilk' gained massive traction on Twitter and TikTok around 2021. The meme's popularity peaked in late 2022 when Pepsi officially embraced the chaos by featuring Lindsay Lohan in a holiday ad campaign titled 'Pilk and Cookies.' Today, the Pilk meme is used to represent ironic enjoyment of questionable food combinations, chaotic energy, and the surprising ways internet subcultures can influence major brand marketing strategies.
