Lupe Fiasco stirred the pot a little bit when he said the Chicago youth movement makes him nervous on a Baltimore radio station.

“Chief Keef scares me. Not him specifically, but just the culture that he represents,” he said. “When you drive through Chicago…The hoodlums, the gangsters, and the ones you see killing each other. And the murder rate in Chicago is skyrocketing and you see who’s doing it and perpetrating it, they all look like Chief Keef.”

Chief Keef responded by calling Fiasco a “a hoe ass nigga” and saying he’d “slap him like da lil bitch he is.”

And it looks like that was the final straw. What followed was the following series of tweets from Lupe:

i have spoken peace only 2 receive vitriol and malice in return. My brother seeks destruction my sister seeks attention paths to nothingness

i’d die for them…but they’d probably spit on my grave…i still will die for them…just bury me in a place far from their reach…Amin

My first true love was literature so i will return to that…lupe fiasco ends here…

The literature thing might catch you off guard until you go back a few years when Lupe first promised early retirement.

“There are other ways besides putting out an album that allow me to channel my creative energy,” he said to ContactMusic.com “And I’m writing a book about a window washer.”

As for the “next album is his last” comments, time will tell whether he’s referring to Lupe Fiasco’s Food & Liquor II: The Great American Rap Album Pt. 1, which comes out September 25th, or its rumoured sequel.
