The first warm day after a cold spell. All of the hot boxes will be out in their sluttiest attire, walking around, or sunbathing. Most will be donating free anal blowjobs in celebration of the glorious day.
I was walking down the street and this box set pulled me to the side on Box Day and domed me off like there was no tomorrow. Hooray for good weather!

a celebration of the last "Ay" of the week, it being "ay" due to a mispronounciation of "day" Ay day is celebrated on the top of a roof of any building with a can of soda. It is required that you be sitting in a chair, preferrably a lawn chair.Once everyone is nestled comfortably in their seats on the roof, you count down from three to 1 and then say "this is Ay-day" then open your sodas simutaniously evrey diffrent week one must drink a diffrent brand of soda

While hanging out in the backyard, all of us friends declared it FMF Day. We went inside and fucked in a pile.
