What is beef? Beef is a noun and it is also a verb. Beef is when you got a problem with someone else such as if I was to say, "Mike and Bill got a lot of beef between each other" or if I was to say "These guys have been beefing seriously for at least a week". You ask what is so special about beef? Well, I love hip-hop and it seems to me as if in hip-hop, beef is the driving force of the selling of albums. For example, Jay-Z and Nas had beef between each other for the longest, and I don't have concrete facts, but I am almost sure that their CD album sales increased by at least ten percent. I think that in hip-hop, skills should just be enough to get you at the top of the charts. Just think, the beef between East Coast and West Coast got Tupac and Biggie killed.
