vacation constipation 

Losing the ability to poop when you lose that home field advantage.

May be a result of changes in eating and drinking habits, elevation, fiber intake, stress, etc.

Vacation constipation is usually followed by a glacier dump.

I'm having a horrible case of vacation constipation...can't wait to get back home and drop a couple belt notches.

Vacation Constipation 

The ability to hold your need to go number two due to an innate fear of going in strange or public places.

It usually happens while on vacation or some other trip, most times because of the fear associated with dirty public restrooms or having to go in the midst of those with you. The constipation can sometimes last for days, a feat seemingly impossible on normal days or at home.

When Noah and I took a trip to Disney World...I had the worst case of vacation constipation. I didn't take a crap for 4 days. I was afraid to use those dirty, puke-filled bathrooms, but man it felt good when I got home!
