In real life, Kelly Oxford is a young housewife who spends her days caring for her three kids in Calgary, Canada. But online, she’s @kellyoxford, a prolific tweeter whose biting, edgy humor (sample tweet: “Hey @Drake thanks for teaching my kids how to sing the n-word so beautifully”) has won her celebrity fans like Mindy Kaling and Roger Ebert… as well as 339,534 other followers at last count.

And as of yesterday, Oxford can officially call herself a screenwriter as well. As Deadline originally reported, the stay-at-home mom just sold a script called Son of a Bitch to Warner Bros. It’s the first feature Oxford has written, though she previously sold pilot scripts to both CBS and NBC. (She’s been with agency WME since 2009.) Her first book, a collection of essays called Everything Is Perfect When You’re a Liar, will also be released this fall.

Clearly, Oxford is a busy lady. But in between fielding phone calls and shepherding the munchkins, the Twitter queen took a moment to answer a few questions via email.

In your own words, what’s your movie about?

The log line was in my own words! It took me an hour to come up with “young stoner who tries to maintain her popular party image even after discovering she’s pregnant.” I think the heart of the movie is just about how major change in your life pulls the rug out from under who you think you are.

How’d you choose that title? It seems to really encapsulate the spirit of the movie.

Hearing people earnestly say “Son of a bitch,” as a true expletive, is funny. And in this context there are two interpretations. I had a few on my list, but this one stuck.

Does Twitter figure into the story at all?

I’ve read a million times that I’m getting a show based on my Twitter. I mean, it would be awesome if a producer just set it all up for me, but that never happened. I’ve just been pitching TV for two years. Twitter factored in with meeting Jhoni [Marchinko, the Emmy-winning screenwriter] and getting an agent in ’09. I’m just a writer who also tweets. There are a lot of us.

The script’s already being likened to Bridesmaids. Do you think that’s a fair comparison?

I love Bridesmaids, and I think Son of a Bitch is being compared because it’s a squeamishly honest R-rated comedy with female leads. Those aren’t very common, you know.

Ideally, who would you cast in the film?

All the funny girls in their early 20s, and funny guys in their late 20s early 30s… This is a trick question. Don’t trick question me, EW. I’m street smart.

Can you tell us a little about your upcoming book?

I’m almost done editing the book, and should be doing that right now. I’m totally horrified by a lot of what I’ve written. I’ll re-read and realize that the most embarrassing actions and moments are so entertaining and character revealing. I kind of revel in giving perspective and making light of the worst things… it’s my thing.
