The Celebrity: Amanda Bynes
The Social Media Blunder: Sent out a tweet that said, "I want @drake to murder my vagina," on Twitter in March.
Why It Was Such A Fail: Do we even have to explain this one? Ms. Bynes said and did a lot of really stupid stuff on social media this year. But this was easily the worst, most vulgar thing that she did.
