Lupe Fiasco is known for his lyrical content, much like rapper Mos Def - or Yasiin Bey if you want to get political. So it was no surprise when Lupe responded to Mos' video where he calls out any emcee to battle him, Black Thought and King Los. "I'm tired of these dudes pretending like they're dope. You're alright, but relax...And we don't have to make no back and forth, corny records about it."

Lupe retweeted the video on Twitter and uploaded a meme on his Instagram that reads "Challenge Accepted." "Dear Yasiin Bey, Whenever, wherever, whoever... Sincerely, Lupe Fiasco," the Chicago artist wrote. He then went on to post a rap, saying "If Mos wanna battle, he can get a whiff of the wrath / And I'm behind all these bars don't need to tap Miller for some genuine drafts." The clever wordplay was clearly a shot a Drake, whose alleged ghostwriter is Quentin Miller. In his next post he tells the "Drake hive" it's not a diss towards the "6 God" as he continues his short rap.
