The Beef: Lupe Fiasco vs. Chief Keef
Why It Was So Unexpected: Aside from the fact that both of these guys are from Chicago and, for that reason alone, should get along, their beef was over something silly. During a radio interview, Lupe said, "Chief Keef scares me," which prompted Keef to take some shots at him on Twitter. And, that led to Lupe to give him a lecture on Twitter, which resulted in Keef saying that his Twitter account had been hacked. Um, okay?
How It Ended: It ended when Keef claimed he was hacked. But, then things got really weird. Lupe said that, as a result of the beef, he was retiring from rap because of "a broken heart." We're not sure if he's still sticking with that decision, but…WTF?
