1. A deceptively dirty-sounding word, usually used to describe the making of forts in suite 402.
2. Overzealous watching of TLC
3. An open-ended term. Usually involves 99 puppies, a horse, and a goat.
Amanda and Jayda had a fortathon yesterday, and have since sold the horse and the goat to a Siamese circus.
