There are four definitions: pickle milk, Pepsi milk, piss milk, and penis milk.
Person 1: "Yo, I want some pilk."
Person 2: "Which kind? We live in a society, a place that speaks a language. You should use it to specify which kind of milk concoction you fucking want. This is on the same level as the god-forsaken places that use "coke" to mean any soft drink, though it would make sense in both ways if they put cocaine in all their sode. We're done, Gerald, and I'm getting a divorce. Fucking illiterate deadbeat."
