The day after Superbowl Sunday.

As a result of our country's tradition on Superbowl Sunday to collectively eat the most deliciously unhealthy foods known to man (e.g. buffalo wings, pigs-in-blankets, pizza, mozzerella sticks, chips & dip, sloppy joes, french fries, burgers etc.) and collectively drink billions of bottles of the cheapest beer, there is no other day of the year to beat the sheer mass of our collective poops, than the day after Superbowl Sunday. I therefore declare it, National Poop Day.
Pat: Hey man, you taking off of work for National Poop Day?

National Poop Day is a day where you and your friends have to poop at least 3-5 times in one day. If not then you have failed poop day and you and your friends (whoever failed) has to stick their whole middle finger up their own butthole.

The day after St. Patrick's Day. Those that celebrated correctly will have green colored poop the day(s) following St. Patrick's Day.
If you're not apart of National Green Poop Day, then you did St. Patrick's Day wrong.
