The 'Phrostie' meme stems from the underground delivery service of hyper-colored, highly potent frozen alcoholic beverages that gained notoriety on Instagram, particularly in New York City around 2014. These drinks, often sold illegally via direct messages, became a cultural phenomenon due to their vibrant layers and mysterious ingredients. The meme evolved to represent the intense 'kick' of the beverage or the sketchy yet exciting process of obtaining one. Today, Phrostie memes are used to describe anything that hits harder than expected or to evoke a specific era of mid-2010s street culture and viral food trends.
