look up any word, like mexican microwave:
An UDism is a term that was made up for, and only exists on, Urban Dictionary. It includes imaginative neologisms as well as just plain disgusting dirty crap. If ever used outside the confines of this Web site by anyone other than the originator, it ceases to be an UDism.
UDism is an UDism, but not the dirty kind.
