Pilk

Pilk is a dirty soda which is made by combining Pepsi and milk.

Background
The concept of combining soda with dairy has existed for a long time. The ice cream float was invented by Robert M. Green in 1874. Doodh soda, a drink made by mixing lemon or lime-flavored soda with milk, is popular in Pakistan and India. The Korean Milkis, Japanese Calpis Soda, and American egg cream are all carbonated milk-based drinks.

Pilk originated in an episode of Laverne & Shirley, during which Laverne drinks Pilk from a large bucket and remarks that it "needs more Pepsi". The drink resurfaced in the 2010s with the dirty soda trend, in which people mixed soda with syrup and dairy, and in 2020 using social media.

In 2021, American singer-songwriter Olivia Rodrigo posted a picture of her holding a cup from Swig, an American soda fountain chain specializing in dirty sodas, causing dirty sodas to gain popularity on TikTok.
