Vampire Milk is when a woman during her period uses a blood clot to mix in with milk, making it chunky and sort of red. Specialized if made with tit milk.
“Hey Mollie! that blood clot you had was HUGE yesterday! You should use it for your Vampire Milk!”
Originating in Uruguay, "Milk Vampire" is a term for a person (usually a young female) who has a thirst for semen. The Milk Vampire will stalk out his/her male prey carefully, using sly methods to trap the victim, such as hiding under tables and striking any nearby male genitalia.
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
