The idea:
A golden shower cursed cannonball, which is a cursed cannonball that can be purchased for a lot of gold. When it hits a ship the effect is that players on board that ship see briefly a golden shower of coins and all get a small amount of gold. What the players get combined is way less then what the cannonball costs. When it doesn't hit a ship it just explodes and you see it raining down coins, like fireworks, and the gold just vanishes.
Why:
There are topics about Pirates finding they have too much money with the request for a gold sink. This idea could be such a gold sink. Shooting these cannonballs is decadent, with whatever intent they're used as they're always a waste of gold. You can just shoot them into the air to show off that you're wealthy. You can shoot them at other ships by means of saying thank you (although they have to patch a hole) or as taunt, or as (an expensive lol) last resort.
Possible variations:
There could be two types of these cannonballs. The normal version and a light version, which differs in the sense that it doesn't do damage to ships. When you're rich in the game and bored you could just sail around and shoot gold at other ships, wasting a lot of gold while doing that.
Edit: I looked up the term which got censored and OMG haha. Ok, substitute that for golden rain.
