Koo-koo-moo

A political or religious fanatic who rarely uses critical thinking when coming to any conclusion related to their own biases and belief systems. They regularly justify their behavior and beliefs without rational explanation while using slander, lies, manipulation, and other forms of subversive behavior against others who don’t think, believe, or act as they do.

The Koo-koo-moo’s showed up to the council meeting and disrupted the entire meeting by being loud, aggressive, and boisterous in an effort to get their own way.
