It’s a metaphor which basically means tell us something we don’t already know. Usually pertains to a conversation about something related to politics or religion but could mean anything . In church there’s always a preacher every Sunday. The choir boys and girls are the people who sing the melodies. So basically the choir has heard everything the preacher has to say every Sunday. Does newcomers would not have heard what the preacher had said. So when somebody says preach to the choir the metaphor actually means that the choir has already heard everything the preacher has to say. So if somebody’s rambling on and on about a subject that you already know about and agree with you could say well you’re preaching to the choir LOL get it?

HR won't hire this guy. They want someone who can "hit the ground running". They must be waiting on a "purple unicorn". I apologize, I'm "preaching to the choir". (LOL. That was 3 metaphors in one explanation. I recommend using Urban Dictionary to look of the other two metaphors)

When a fundamentalist christian gets so angry/excited about God over the internet that they start to type in all caps. While typing in all caps, they forget to use punctuation marks except for the occasional "!!!!!." These christians have been known to spew out mass chunks of angry bullshit in huge blocks of text. They end the block(s) text with "I'LL PRAY FOR YOU" or "YOU ARE LOST YOU ARE GOING TO HELL."
