Valentines Day is for the lovers, this day is for the fuckers. A day for cake and eating out- show your women some love on this auspicious day in return for the careful cooking and blowing that was bestowed upon you during steak and blowjob day. Eat your cake boys.

whatever the opposite of steak and blowjob day is, do that.
