A set of rules governing action and property ownership in and on any ocean, based on the belief that any item(s) discarded into, or left unattended for an extensive period of time, an ocean is/are considered forfeited. Due to the forfeited ownership of this/these item(s), any individual who finds the item(s) may claim it/them as their own.
Person 1: "Dude, I think a dragon just stole my boat!"
Person 2: "Nah man, you left that there for like three days. She's just following Ocean Law."
If an item is in the ocean long enough, it's yours. You can do anything in the ocean.
Meanwhile in our beach school trip
My Crush: What do you mean I'm yours?
Me: Sorry dear, its the Ocean law
