Katy Perry is currently in the middle of an ugly Twitter spat with Chicago MC Chief Keef (well, the “ugly” part is all on Keef’s end). Perry recently tweeted about Keef’s song, “Hate Bein’ Sober,” saying “Just heard a new song on the radio called ‘I hate being sober’ I now have serious doubt for the world.” In terms of insults, that isn’t even up to the level of the light ribbing Diplo lobbed Daft Punk‘s way. Pretty harmless. Well, the eminently reasonable Chief Keef took major offense, and also took a page out of the Chris Brown Handbook of Twitter Etiquette (always a wise career move!), throwing a couple misogynistic tweets her way – including one in which he said he’d “smack the shit out of her.” Classy, bro!

For those of you not up to speed on Keef, here’s the CliffsNotes version. He’s a controversial figure in the hip-hop world, inspiring many a thinkpiece. Kanye West helped fuel the kid’s rise when he highlighted “I Don’t Like,” but rap fans are divided on Keef’s music – does he make mind-numbing bangers or does he tap into a grittiness that’s been missing from rap recently? But he’s mainly a flashpoint because of his generally contemptible behavior: Keef has been arrested on drug and gun charges, he has been involved in a shootout with police and he celebrated the death of one of his rivals via Twitter. So, yeah.

Dude’s only 17, so you can chalk this stuff up to him being a dumb, idiot teenager just like all the dumb, idiot teenagers acting like dumb idiots, but this is another off-putting episode in the rapper’s short career. Anyway, head below to see the SMH-worthy tweets. More »
