A French Weekend is not necessarily a weekend. Essentially, a French Weekend is the few days you don't wash-up after having steamy, sweaty, hard sex with someone you just met and feel very turned-on about. For the next few days you can smell sex on yourself and the scent of that person still lingers on your body until it's overtaken by your own familiar stink. That's when you know it's time to rub-n'-scrub with shampoo and good soap and go fuck again.
I haven't seen her for a few days now, but I'm still having a French Weekend.

Man, you smell like that chick from accounting. Are you having a French Weekend?

Why are you constantly sniffing your fingers this week?

Get the french weekend mug.
A weekend in which one does nothing productive and has little social interaction with others. For a true french weekend, one must not leave one's home/dorm at all on Friday or Saturday. Usually, one gets more than 24 hours of sleep on friday and saturday nights combined. Lots of leftover food, ramen noodles, and/or Domino's is consumed. Personal hygiene is neglected; Masturbation occurs frequently. French weekends wind down on Sunday afternoon, when one cleans one's living quarters and takes an excessively long shower, in which the balls are washed thoroughly. Only after this thorough washing of the balls may homework or any preparation for the week ahead begin.
Dude 1: "I had a great weekend. What did you do this weekend?"

Dude 2: "Literally nothing bro. I had a French Weekend."

Dude 1: "That's awesome dude. You're so lucky."
