When someone preaches some truths, you use this phrase (usually in comment sections online) as a way of agreeing.
For instance on Facebook you may have:
Person A: "You should never blame a whole group of people for the actions of a few people within that group!"
Person B: Say It Again Louder For The PeopleIn The Back.
