"Preach" has no single meaning, but is used to convey a casual sense of affirmation, acknowledgement, Said in agreement, something that is real, absolute, well said, a person dropping mad knowledge,

Or to indicate that something has impressed you favorably.

Its usage among young blacks has been parodied ad nauseam among clueless suburban whites.

There is no single meaning, but is used to convey a casual sense of affirmation, acknowledgement, said in agreement, something that is real, absolute, well said, a person dropping mad knowledge while unconsciously projecting who they are onto others and exposing him or her self as a hypocrite.

Or to indicate that something has impressed you favorably but everyone really knows the person doing the preaching is clueless and talking out of their ass.

Its usage among young blacks has been parodied ad nauseam among clueless suburban whites who actually do have a clue and calling out their counterpart who are the ones who actually have no clue.

Dawg's response... "preach..."

Elmer... "You are the one who obfuscates damn near everything, so you can soothe your self-righteous ego. You like to do that, so you can twist the conversation back to your positions and try to put the others on the defensive. Few exceed your mastery of that kind of arrogance - truly."

Fudd... "preach."
