Nickname given to LeBron James, small forward for the Miami Heat, paying homage to his two most memorable feats: (1) when he shit on the entire city of Cleveland by announcing on LIVE TV that he was leaving them for Miami, (2) when he choked harder than anyone has ever choked before, during the 2011 NBA Finals.

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.
