Another name for Church.
Often used to evangelize your based but non-Christian friends. Instead of asking them to join you for church, you can ask them to join you to the Based and Christpilled-convention.
Person 1 (based Christian): Hello there my fellow based individual, would you like to join me in going to the Based and Christpilled-convention this sunday?
Person 2 (soon to be based Christian): Sure. That sounds very based, and I’m sure it will annoy my cringe libtard, blue-haired cousin.
