Mos Def seems to be inspired by the recent wave of rap beef, and he's ready to take on a battle of his own. The rapper shared a video challenge today, suggesting he, King Los, and Black Thought could take on any rapper in a battle. 

It didn't take long for rappers to start responding, with King Los co-signing the challenge, and Lupe Fiasco starting writing some mock bars (including one with a Quentin Miller punchline).

Meanwhile, Mickey Facts went as far as to set up opponents, pitting himself against Kig Los, Daylyt against Black Thought and Lupe against Mos Def.

It definitely escalated quickly, but we're still not sure how serious everyone involved is. Take a look at the twets and Instagram posts below. Which battle do you wanna see the most?
