On Sunday evening, the singer's Twitter account was deactivated (and then he deleted it all together) after he went on a verbal tirade against comedic writer Jenny Johnson that exceeded 140 characters.

Johnson, known for her humorous tweets, re-tweeted a post from Brown where he complained that he looked old and added this snarky comment: "Being a worthless piece of s--t can really age a person." But Brown wasn't laughing. The 23-year-old responded by unleashing a foul barrage on the woman over a series of tweets ... before Twitter stepped in and froze his page.

"Take them teeth out when u S—king my d--k HOE," Brown tweeted to Johnson, who has nearly 300,000 followers on the social network.

After she corrected his spelling of the word "ho" (since his version described the gardening tool), he snapped, "I should fart when ur giving me top" and tagged #SiezeTheDay, which is the name of his current tour. To that, Johnson retorted that Brown's mother should be so proud of her son's vocabulary. "Mom says hello," replied Brown. "She told me not to shart in ur mouth, wanted me to s--t right on the retina."

After Brown and many of his millions of followers flooded Johnson's mentions box in retaliation, she waved the white flag and tweeted, "Okay, I'm done. All I got from that exchange with Chris Brown is that he wants to s--t and fart on me."

The "Don't Wake Me Up" singer revelled in what he considered winning the virtual fight. "Let me leave this bitch alone," he wrote. "It's good to know my worth by listening to a bitch that is worthless ... Teambreezy had fun today!!! Outta here bitch." When Johnson noted she has "zero respect for a person who seems unapologetic for the terrible crime he committed," Brown ended the feud with this final, shocking tweet: "Just ask Rihanna if she mad."

On Saturday, the "Diamonds" singer proved she's not when she tweeted a photo of Brown passed out face down on a bed without his shirt on after the two spent Thanksgiving together in Berlin.

Brown may have been off Twitter, but his fans still carried on his work. Johnson wrote on Monday morning that she was receiving death threats from so-called members of Team Breezy. "It's alarming how many death threats I'm receiving via @ replies," she tweeted. "I encourage everyone, including @twitter to look through them. Not cool."

Brown's Twitter page later popped back up ... but with his offensive tweets deleted. Soon after, the page was down again.
