Definition: A group or organization.
Sample usage: “I joined an aggrupation that shares my fascination with our occupation.”
Popularity: Why you’d use it instead of “group” or “organization” is a mystery, especially when it could be redefined to mean a grievance with one’s job assignment: “This project I’m doing gives me so much aggrupation.”
