Traditionally celebrated yearly on the first weekend of December, but it's popularity has lead to the expansion of the holiday to multiple times per year. Average to good looking males who participate in Ugly Slut Weekend, or, USW actively seek out below average to ugly girls for sexual activities.

Alcohol is not required but heavily recommended for the males to further decrease the already small chance of actually skeeting inside the ugly slut and risking a baby mama relationship in future

"No Slut Left Behind" is a the trademark slogan of USW. As an excerpt from it's mission statement reads: "to bring weiner to every slut in the world, no matter her physical appearance"
I heard Ugly Slut Weekend started at SJU, which I can definitely believe considering the amount of Jersey girls that go there
