Also known as thanksgiving, a day where we forget about the rules of portions and stuff ourselves with plenty of good food.

National fat ass day is on August the 22nd and if you have a fat ass you have to let your friends slap it and can't complain about it.
*slaps ass*

Josh: bro what the fuck why did you slap my ass
Ethan: Bro it's national fat ass day I can slap it all I want
Josh: Aw man fine since it's national fat ass day
*Slaps ass again*
