A day to focus on your hate for your ex, and think about how they'll realize someday you are pretty much the Bee's Knees. A good day to get scandalous, go on many dates, and maybe texting your ex a Drunken hate text!
Josh: Yeah, I was celebrating National Eff the Exes Day.
Joe: There's a holiday called that?
Josh: Yeah every January 21st!
Joe: Cool! What did you do?
John: Well, I went on a super date with the entire college cheerleading squad, drank a 1.75 of Vodka, and finally texted my ex a pic of me giving her the middle finger whilst laying out a Cleveland Steamer on the Cheer Captain's chest!
Joe: HEYOOOH!!! Good riddance to that whore!
