Rapper/actor Ludacris insists the only reason he talks about his "balls" so much is because he insists they have been instrumental in his success. The CRASH star admits he has used the phrase "balls" as a euphemism for courage so often, he has become particularly protective of his nether regions as a result. He says, "You put your balls on the line. That's how you become successful if you weren't born into money. "Which maybe goes into why I talk about my balls so much and why I don't want them to get cut off in a movie. Because all I have are my balls and my word."
