Just when we thought the beef between Young Thug and Metro Boomin was over, they're just getting started. But this time, Metro is actually instigating the fight.

"I'm in the city @ the spot right now bra and we know each other in REAL life so u can pull up whenever kuz u know I ain't no hoe," Metro tweeted whiling adding a mention of Young Thug's Twitter handle.

Their war of words began earlier this week after the producer went on a Twitter rant criticizing rappers who saturate the market with mixtapes -- according to him, only Future has mastered it. Things seemed to settle down after Young Thug tweeted "but f--- it we ball!!!" but now he's back on the prowl. He retweeted Metro's tweet to "pull up" and added a smiling emoji as if to say "that's cute." But things escalated fast as Thugger promised that he's gonna "beat the s--- out u fool..." Yikes.

It's unclear what sparked Metro to call out the "Stoner" rapper -- especially since on Wednesday (Nov. 11) he claimed that his initial rant wasn't even about Thug. "You gotta be crazy if you think I subtweeted Thug. That’s corny. People are allowed to believe what they want though. True or not,” tweeted Metro Boomin.

Young Thug, on the other hand, said he had nothing against the DS2 creator and even called himself a fan of the Freebandz leader. "I have nun in the world against future I listen to his music His music makes me happy and I hope he continues to bless me and others with it," he wrote.

Now the fighting words may just become a reality. Stay tuned to see what social media drama unfolds next between these two and check out their tweets below.
