Christmas dump 

A Christmas dump is such a universally experienced phenomenon when one enormously relieves themselves after the holiday season, having eaten all the good food.
This term can be used for other holidays as well, ie. Thanksgiving dump or just simply Holiday dump.

Oh, man I just had my Christmas dump, it was crazy!
I’m glad we are finally home, I have to do a Thanksgiving dump.

Post-Christmas Dumping

A popular, yet unheard of holiday tradition that usually takes place the night of Christmas or at any point in time on the day after Christmas. In this tradition, one locks his or herself in a bathroom for an unusually large period of time and painfully excretes all holiday fruitcakes consumed over the past few days. This tradition is a wonderful way to say say goodbye to the Christmas season and to prepare your bowels for the upcoming new years.

Brian: That was a great Christmas season. Best Christmas ever!
Jimmy: Yeah it was! But now it's time for the Post-Christmas Dumping. See you in a couple hours.
