Pertains to and when something out of your own control (or seemingly out of your own control) goes totally wrong and has negative consequences. "The Steamer" loves everyone despite everyone despising "the steamer."
Losing a sports video game at the very last second. Dropping your beer. Getting in a car accident. Pouring your cereal only to find not enough milk. Your girlfriend cheating on you. Steve McNair coming one yard shy of a superbowl victory. All of these are just some examples of "the steamer" and how it ruins our day by loving us.

Taking a huge dump right before entering the shower. The steam magnifies the stench and incapacitates all those who enter afterwards.
I fired off a steamer a few hours ago and when I came back to the bathroom, there were three people lying on the ground unconscious.
