amen corner
1. An area of seats in a church that is occupied by ardent worshippers. Aunt Mildred goes to church every day, so she sits in the amen corner on Sundays, while we're stuck in the back of the congregation.
2. The tireless supporters of a person, group, or cause. It's a good thing that councilman has his amen corner to rally behind him, because none of the townspeople support his new bill!
