Lebron is a slang word for "blow" which is a slang word for cocaine. Prior to the start of the basketball game, Lebron James powders his hands and throws it in the air similar to something you would see Al Pacino do in Scarface.
Mo: Last night was wild.

Krackis: Oh yea? What'd ya get into?

Moseph: I partied with Lebron...

Krackis: Lebron keeps the party going all night.

The act of being a ball hog the ENTIRE game but yet still being able to keep the score or lead close..until the final minutes where you choke and blow the game if and ONLY IF you are playing a good team
Kendell dominated the entire game but he pulled a Lebron and we lost the championship game.
