A college prank that probably has other names. Most commonly played in college dorms. The act of filling a trash can about halfway with water. Then you lean said trash can against a door. Knock on the door and run like hell. When the sucker goes to open the door, they get the onslaught of the water, going everywhere. I call it the Johnstown Flood as I attend the University of Pittsburgh at Johnstown, and the name fits perfectly, if you're familiar with the town's history
