The act of degrading a female during intercourse. Most common is when your boys run in high fiving you, and you continue to high five while continually pile driving said female. Other methods include screaming bizzare phrases such as "This is Sparta!", power bombing her, or really any type of shenanigans. Bonus points if you finish, and she doesnt call the police.
