The Celebrity: Chief Keef
The Social Media Blunder: Started a Twitter beef with Katy Perry in May and threatened her. After Perry criticized his song, "Hate Bein' Sober," Keef took aim at her. "Dat bitch Katy Perry Can Suck Skin Off Of my dick," he tweeted. "Ill Smack The Shit out her."
Why It Was Such A Fail: It would have been one thing for Keef to send out one angry tweet about Katy Perry. But it was quite another for him to send out several tweets and then to threaten her with violence. He definitely didn't have to take it there.
