A bit of troubling news in the world of hip-hop tweets: Lupe Fiasco has tweeted that he is quitting hip-hop in the wake of antagonistic messages and harsh responses to his song "Bitch Bad," which demands other artists reconsider the use of the word in their tracks.

The Twitter account associated with Chief Keef, the Chicago rapper best known for "Don't Like," a song amplified by Kanye West when he snagged it for his upcoming G.O.O.D. Music compilation Cruel Summer, sent out the following tweet on the evening of Sept. 5.

Lupe fiasco a hoe ass nigga And wen I see him I'ma smack him like da lil bitch he is

Though Keef later said he was hacked (a familiar excuse to hip-hop fans; Keef also backtracked tweets that attacked Lil Wayne and recently murdered rapper Lil JoJo, the latter of whom Keef mocked after the murder), the message appears to have shaken up Fiasco:

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

Lupe Fiasco
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

Lupe Fiasco
This album will probably be my last...its been a pleasure to have all my fans provide so much love an inspiration for me and my family

Lupe Fiasco
but my heart is broken and i see no comfort further along this path only more pain. I cannot participate any longer in this...

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

Fiasco has repeatedly called for an end to gang violence in his native Chicago. He had previously said he feared the culture rappers like Keef were perpetuating. "The murder rate in Chicago is skyrocketing and you see who's doing it and perpetrating it, they all look like Chief Keef," Fiasco told Baltimore's 92Q.

The rapper recently broke into tears during an interview with MTV's Sway after being shown a vintage video of his neighborhood. A number of people shown in the video had either been killed or incarcerated. Describing what it was like to see those "ghosts" overwhelmed Fiasco with grief.

"Bitch Bad" has caused some disruption in the field. West took to Twitter for a monologue of his thoughts on the word. West, who has an unreleased song titled "Perfect Bitch" (about his girlfriend Kim Kardashian):

Kanye West
I usually never tweet questions but I struggle with this so here goes... Is the word BITCH acceptable?

West's tweets are worth a read. He eventually ended his mini-rant by posting Lupe's video.

HuffPost Entertainment has reached out to Fiasco for comment. As a parting thought, here's a line from Fiasco's song "Words I Never Said": "My problem is I'm peaceful, and I believe in the people."
