an alcoholic beverage, typically in double shot size, that consists of 1 part gin and 1 part milk. the milk is given in a rocks glass, the gin in a shot glass. to shoot, one must pour the gin into the milk and take down immediately.
"dude, you're late for work again. screw it, let's just stay home and take gilk shots all day!"
Gross milk is synthetically created by letting a gallon of milk sit in the fridge for 2 months until it has fully curdled and smells gross. This process can be sped up by letting it sit outside in direct sunlight on a warm day.
My friendhid a gallon of open gilk in my bedroom and now I don't sleep there anymore.
