Definition: The Best Kind of Beef
Example(s): Jay Z vs. Nas

Kobe. Wagu. The dry-aged porterhouse at Peter Luger's. This is the good stuff. The best rap beef is the kind that brings out the best in both its participants. Feeling disrespected and underappareciated in his home city of New York, Jay-Z writes "The Takeover." Which then lights a career-rekindling fire under Nas's butt. This is the kind of beef where everybody wins—especically rap fans.
