a statement someone makes or "proclaims" when he/she needs to go to the bathroom, like the emancipation proclamation, except for peeing
"Yo, I gotta use your bathroom, I'm about to make a urination proclamation, I've been holding it in for like 3 hours!"
When you laugh so hard that you pee your pants, and then mention it to your friends.
Marty: Hahahahahaha. I just peed my pants.
John: Ew. Dont give me a urination proclamation.
