What is Jk Rowling?
1.
Used in place of "jk", to denote any previous comment as having been in jest.
Also can be used in conjunction with other harry potter references, where appropriate, as in:
Person A: I thought you were jk rowling!
Person B: No, I was totally being sirius black, I meant what I said!
Person A: Well fuck you... Professor... Sprout!
Person B: lolwut?
(JK rowling and sirius black are the only ones that really work together)
