Dirty Watermelon 

Get the biggest watermelon you can find and put a hole into the melon, then shit (or piss) into the melon for three days and wait for the watermelon to rot. After this throw the melon at your enemy's.

I almost killed a man by throwing a dirty watermelon at him

Dirty Watermelon 

When you have the bubble guts and tell your bitch to lick your asshole and shit in her mouth. Thus having dirty water on her melon.

Paul ate too much spaghetti and had a stomach ache, during copulation with Becky he asked her to lick his anus not knowing he was about to bust a Dirty Watermelon.
