beef
When rappers aren't good enough lyricists to have fans or just want some publicity, they will copy Tupac and Biggy and set up a beef with another rapper.
Their auidence of mainly wannabe gangsta rich white folk love this because if they meet another wannabe gangsta who listens to a rival of their favourite rapper, they are allowed to exchange poorly thoughtup insults such as 'yo mama'.
The Game: Grrr...I am rich, famous but I am street which means I am required by law to have a beef with another rapper. 50 cent is fake and so is G-Unit.
50 cent: I am not fake even though after that shooting I am now 76% mechnical parts. I mention my shooting as much as possible because it means I am hardcore and it doesn't occur to people that the shooter was just a lousy shot. I am hardcore so buy my records. If you buy my records, that means you are hardcore, who cares about artistic talent? You're out of G-Unit The Game.
