A sex position in which you wait for your partner to visit the bathroom, and once they're inside you must run at the screaming "INDOMINUS REX" while scratching them and growling like a dinosaur. Once they say, "What are you doing?" you push them out of the way and take a piss on their face.
Girl: "Babe, when we get home, I'm gonna Indominus Rex you so hard."
Guy: "Who the fuck are you? Get out of my car, please, or I'm calling the police."
Guy: "Who the fuck are you? Get out of my car, please, or I'm calling the police."
