When a person has never heard of something and automatically believes you're wrong, crazy or it doesn't exist.
"I moved to a small rural town, and the arrignorance is astounding." The following example can also be used- "I am surrounded by arrignoramuses."

An ignorant or stupid person but arrogant enough to believe if they haven't seen it or heard of it, it doesn't exist.
The guys I work with grew up in the same 50 mile area, moving from out of state and being exposed to many cultures and diversity, I was floored when the arrignoramuses thought I was crazy when I said "pomegranate". I learned that these mythical fruits simply do not exist.
