time between Halloween and New Years when one gains obscene amounts of weights in one's ass and/or belly due to extreme feasting and binge eating on candy, turkey and, Santa's cookies.
Rudolph said to Santa, "hey fat ass lay of the cookies. You've gained the Hallowthanksmas 50 and I have to haul your obese extremities around the globe."

Is the holiday celebrating the most wonderful time of the year, October through December. It is a time of great warmth, sharing, parties, and of great American commercialism. People complain about overlapping holidays, but why? The distinction between the three major holidays is only becoming less clear. Embrace it as Hallowthanksmas! It's certainly not going to disappear. It's a great excuse to eat, drink and be merry for three months straight! Each month is a celebration of its respective holidays, and seeing decorations and stores fully stocked should get our creative juices flowing; food, friends, parties and decorations are all a part of the holidays. Let's face it, Hallowthanksmas is here to stay, and I say God Bless It. And God Bless Us, everyone!
Hallowthanksmas is the best time of the year!
