Say It

"Master Blaster: Who... run... Barter Town? Aunty: You know who. Master Blaster: Say. Aunty: Master Blaster. Master Blaster: Say loud."

- Mad Max Beyond Thunderdome

If a former friend, former ally, enemy, political rival, or just someone you hate or like to make fun of wants your help, or a favor, or just to get in the clubhouse, why not make them grovel a bit before helping them?

Sometimes used by villains as part of trying to make a hero Kneel Before Zod.
