An obscene and unsanitary derivative form of baseball popularized in New York City.
The structure of the game is largely subjective and may be modified in accordance with the wishes of its often roid-raging participants.
The term is said to have been created by illegal immigrants aboard the Colombian ship "Sepulveda" and rapidly spread to various Colombian and Dominican enclaves throughout New York City.

Facebook balls refer to the harsh, rude things that people might say on Facebook that they wouldn't say in person.
Rob posted on Facebook that Larry's girlfriend is a total dog. He would have NEVER said that to his face. He's got some big FBB's (Facebook Balls). Then Larry posted back that he was gonna punch Rob in the face. The FBB's must be contagious.
