LET IT BE KNOWN 

This means LISTEN UP MF'ER! Youre about to hear something important and you WILL be held accountable for the info. It's accompanied at times by ringing in the ears, headache , and blurred vision. A LET IT BE KNOWN can be in verbal or written form.
They are usually ineffective because the non-listeners are often dumbasses but they are still accountable for the info.

Dr Phil--Dod you tell Gregor about his ass?
Krystola- ahhh, Imma wait and beat his ass when he gets outta jail!
Dr Phil- Woosah Krystola, I have several issues with that. You should atleast do a LET IT BE KNOWN announcement.
