A large off campus college house in which sorority girls from the ages of 18-22 live, eat, sleep and mate with other Greek life individuals. The house usually consists of 10 or more sorority girls who are all in the same sorority. In this castle that they live in, they drink and have sex, and then drink and have sex some more. The living conditions of the castle are horrifyingly and disgustingly dirty, however the bond that they have with their sisters make up for the poor living conditions of the interior of the castle.

"Dude you're not gonna believe this, but my pledge brother pulled it with the entire slut castle!"
