Trigotry

Trigotry: noun. The act of being prejudiced against three types of people at once. A common form of trigotry is behaving hatefully towards people of a different gender, religion and races. Other, slightly less common combinations include hatred towards a different race, religion and gender. There is no such thing as a tetragot or a pentagot, because when the number of hated people increases so substantially, it is not worth it to keep track anyway (unless, of course, all of these people join and come to your house at night, in which case you should hide under your bed and put a large figurine there in your stead).
