flowjack 

1: Originally, a synonym for "retarded person." This usage has lost its effectiveness.

2: Name for the head M.C. of BCCB, because he is a jack-of-flow. He can drop beats like a mother-fucking farmer, yo, who accidentally dropped an entire crate of Beets, which he intended to sell at the local farmer's market, but which he can no longer sell because they are so bruised from the fall.

1: Normie: Hey, Albert. I'm talking to you, Albert. Pay attention. What you are, Albert, is a flowjack. Okay? Got that? So, from now on when I ask you what you are, what're you going to tell me?

Albert: Huh?

Normie: What are you, Albert?

Albert: A...person.

Normie: No! You're a flowjack, Albert. A flowjack. Okay? Now, what are you?

Albert: I'm a flowjack.

2: "That Flowjack sure is mother-fucking bomb-diggity. Listen to him as he blows us all away with his divinely-inspired word-rhyming, and with his superior grasp of syntax."
