J.K. Rowling slams Twitter troll in the best way possible

J.K. Rowling isn't one to shy from speaking her mind. The Harry Potter author recently took to Twitter to slam a user who had claimed that "Serena Williams is built like a man."

After Rowling posted a supportive tweet for Serena's big Wimbledon win, a trolling Twitter user commented that is is "ironic then that main reason for her success is that she is built like a man."

But Rowling was not having it.

In retaliation, the British author posted this:

Burn.
