A week where anything goes sexually with your partner. Neither party is allowed to say no to any proposed sexual idea, thus it devolves into some dirty whoring.
Ideally you get your friends to get in on DWW as well so you can compare notes and share ideas. More importantly it allows you to push down the shame every morning when you reflect on the prior days activities and enables you to get through the week.
You might set aside a budget because sex toys, lube and restraints aren't cheap which is how you're going to feel by the end of it all.
Also known to save many a marriage. Should be done at least once annually.
I got a facial, anal and about 30 bruises after dirty whore week this year.
When you get hammered to the point of remembering nothing, making a complete fool out of yourself, pissing a lot of people off but refusing to hear the stories when your friends tell you about them. Rather, you'd prefer to hard delete the night act like it never happened.
Friend: Do you remember last night calling your ex and telling him he was the love of your life and you'd never love anyone like him, then using a wedding china to make nachos only to break it and spilling a glass of red wine all over your cashmere sweater.....
You interjecting: I don't need to hear any more. Let's hard delete last night.
