Slut Nation is a word that describes females in general. "All girls are sluts, except my mom."
Slut Nation ranges from the occasional slut, who will maybe get with you after the third date...to the super slut who will fuck you before she knows your name. The origin of Slut Nation came about during an annual beer pong tournament in Arizona that consisted of a 10 girl team. Their drunk Captain didn't know all of the their names and while cheering them on dubbed them all sluts...then decided to shout Slut Nation at innocent bystanders.
Slut Nation was born.
"Ugh, those guys were not worth the way I feel this morning...I totally pulled a Slut Nation." <=Direct quote from a slut.
