The 'Liquorice' artist became furious when Kreayshawn retweeted a link to her video for '212' which originated from pornographic website PornHub and launched a slew of assaults at the 'Gucci Gucci' star on the social networking site on Wednesday (January 4).
"@Kreayshawn you think you're funny? You're a dumb bitch. And you can't rap. I'll sit on your face. ... Fall back sl*t," she wrote.
However, she soon continued: "Lol. This is how bitches wanna start the new year? They want their mics ate this early? Omfg. Why f**k with me tho? What have I ever said about you or done to you for that matter? Ok. Ok. I'm done. This is silly."
Kreayshawn seemed not to respond to the controversy until later on Wednesday, when she asked Banks, "Huh? What did I do to you? I've been listening to your music all month. Strange. Stranger!"
However, she soon after deleted the tweet, replacing it with: "Did I just get smashed on twitter because I was supporting a fellow female? I sure did... *confused*"
Banks immediately fired back yet again, saying "whatever. Of All the things to rt, u rt something from pornhub. pick your fights more wisely. And when u do pick one don't switch it up once someone's at your neck.
"you're always tryna be cute and funny but your not built for it. Really your (sic) not."
Banks then claimed that she would end the feud, posting: "Ok. From now on I will no longer react to any shade thrown my way. Especially if said shade thrower is trying to be subliminal and sideways. Subliminal shots are #p***y .... And not the good kind."
Banks took third place on the BBC Sound of 2012 poll this week.
Meanwhile, Kreayshawn is anxious to release new material as she feels it will 'shut everyone up'.
