Joanne Katherine Rowling. Writer of many short stories and the famous Harry Potter series. She has written the following published books:
Harry Potter and the Philosopher's Stone/Harry Potter and the Sorcerer's Stone
Harry Potter and the Chamber of Secrets
Harry Potter and the Prisoner of Azkaban
Harry Potter and the Goblet of Fire
Harry Potter and the Order of the Phoenix
Harry Potter and the Half-Blood Prince

these are all great books, as many have said. They are not meant to convert people to 'devil worshipping' or anything else that the Pope and/or other people have acclaimed to. It is merely for entertainment purposes and a job for a well-deserving mother.
Person 1:Have you read Harry Potter and the Goblet of Fire?
Person 2:No, who's it written by?
1: J.K. Rowling.
2: Do you know their real name?
1: Joanne Katherine. And Rowling is pronounced like you can row a boat. not a row like a quarrel.
2: Is the book good?
1: OH YES! its my favorite in the series.
2: Are the movies better than the books.
1: By far, no. I think its because I can expand my horizons on imagining what I want to imagine. A based-on-a-book-film is just one person's point of view on a book.
2: I think I'll read it now!!!

(also known as Jo Rowling by her loyal fans) One of the most famous writers of our times. Author of the Harry Potter series, the best-selling books of all times (besides the Bible, of course). Although her books are considered "children books" by ignorant muggles, they have become more mature as the protagonist, Harry Potter, gets older.
I want to meet J.K. Rowling so I can ask her dozens of questions.

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)

Author of the world-dominating Harry Potter books.

Started living off state benefit in a grotty flat with a love child and ended up being richest, best-selling novelist of all time (probably).

'jk' is short for joking, kind of like 'lol' in a way, then 'rowling' is rolling on floor laughing (rofl). so together it means im just joking and laughing my head off with the added pun of being j.k rowling the famous author.
"Wow he's really hot"

"Um are you being serious"
"No hahahaha I'm jk rowling you"

A phrase used when you wish to trick another into believing that someone (fictional or otherwise) is dead, when they really are not. Derived from the conclusion of Harry Potter's 7th installment, in which the author declares in so many words,

"Hey guys, our Hero is dead!!

...jk I fooled ya'all :)"
Tom: Dude last night your mom had a stroke after I was through with her.
Mike: ...
Tom: Don't worry man! JK Rowling!
