First is the Worst's definitions
A sex move where the guy pulls out, ejaculates into his hands, screams "WITNESS!" and throws the contents of his hands into the air, similar to the Lebron James chalk-throwing before games.
Make sure when performing the Lebang James, you throw it away from you, otherwise some may land on you.
