Chris Brown is really bad at public relations. The 23-year-old rapper went on a memorably vulgar tirade against comedian Jenny Johnson on Sunday and apparently realized soon thereafter that it was a bad idea, because he scrambled to cover his tracks. But deleting tweets does not erase their previous existence and deactivating your Twitter account does not take away all of the bad things you did with it.

We're getting ahead of ourselves, though. Did you hear about Chris Brown's memorably vulgar tirade against comedian Jenny Johnson on Sunday? It was truly despicable. Johnson, if you haven't heard of her, is pretty big on Twitter and pretty funny, too. She's also deeply disapproving of Brown's existence, more specifically his history of beating women. And she didn't miss a chance to take a swipe at Brown on Sunday, when he complained about his appearance. "I look old as fuck! I'm only 23..." Brown tweeted. " "I know! Being a worthless piece of shit can really age a person." Johnson replied.

Then things got ugly. In a series of tweets, Brown told Johnson to suck his dick, threatened to fart on her, threatened to shit and called her a "ho" about seven times. After tweeting -- and this is a direct quote -- "mom says hello... She told me not to shart in ur mouth, wanted me to shit right on the retina, ....#pinkeye" Brown tweeted, "Just ask Rihanna if she mad??????" You can read the entire exchange here.

Brown's rant was not well received by the Twitter community or the media. Then again, at this point, it's not like anybody expected more from Brown. This is the same guy that dressed up like a terrorist for Halloween. It's unclear how or why, but within a couple hours of the blowback, Brown's Twitter account was gone. We'll let you know if we find out any more details. For now, we're going with Eli Braden's theory: "Chris Brown's publicist finally figured out his Twitter password."
