CBJ

Stands for "Crybaby James"

Nickname for LeBron James, on account of he's always crying like a little girl whenever the refs make him sad.

"CBJ just elbowed that dude in the defender in the face."

CBJ cries, acts confused, and gets his way like always.

Ref calls foul on guy who got elbowed in the face.

(I guess he shouldn't have headbutted CBJ's elbow...)
