Rusty milk is when you’re having sex with an absolutely gorgeous girl. And all of a sudden your dad who you have not seen the past 18 years of your life suddenly walks into the bedroom while you’re in the act of clapping cheeks, takes the beautiful girl and pours the gallon of milk that he said he would get into her asshole and makes you drink the milk out of it. He then gets her pregnant and leaves to get another gallon of milk, thus the cycle repeats
