Celebrated on the September 17th to mark 260 days of the year (leap year-261 days), the approaching end of summer and wife appreciation day.

Celebrate female sexual freedom and release your natural sexual behaviour.

Have sex with as many people as you can, if you have a partner, why not have some threesomes or a gangbang, and if you're really feeling sexually free, allow those juices to flow naturally, and enjoy the pleasure of removing all barriers.
Do you fellas want to have some fun, it's Natural Slut Day today, and I'm Horny.

October 31st at WHS, also know as halloween. All of the popular girls (mostly cheerleaders) use this day as an excuse to dress up in very slutty costumes.

Examples From Halloween '04: naughty nurses, angels, devils, genies, and costumes invovling fish net stockings
Rob: HOLY SHIT! Did you see the naughty nurses?
Matt: OH Yea! I would tap their asses any day.
Rob: I'm gonna go look again.

First day of each year where the temperature rises above 70F in regions of the US where temperatures in the winter months average at 30F and below. This day is characterized by excessive sunshine and general highs from a sense of spring in the air which prompts white people to wear revealing summer outfits that show off the pale, white skin they have been hiding all winter under peacoats and scarves.
"Man! Guys in tank tops on the quad? Girls with their short skirts exposing their painfully white legs? It's only March 21st! Is it White Slut Day already?"

Halloween. That blessed day that occurs once a year when every young woman knows she can get away with dressing just as sluttily as she wants. Characterized by drunken parties, slutty costumes, fishnet pantyhose and lots of tipsy girls lurching around in hoochie heels they obviously don't know how to walk in. Thank you, American costume industry!
I fucking love Dress Like A Slut Day! You get candy and dick all at the same time!

Dress Like a Slut Day is awesome! You hang out at the bars with all the drunk Nightshift Nurses, Slutty Schoolgirls, French Maids, and Naughty Cops tottering around in their slutlettos. Then you pick one up and bang her!

Dress Like A Slut Day lets me dress the way I wish I could every day...
