J.K Rowling is having a busy year: Harry Potter not-quite prequel Fantastic Beasts and Where to Find Them is in production; the Potter not-quite sequel Harry Potter and the Cursed Child is dropping this summer, and a new Potter concert series is happening. But somehow, even though her life is busier than Weasley’s Wizard Wheezes on April Fools’ Day, she still finds time for Twitter sass. She recently outdid herself by using a Chamillionaire pun to shut down a hater.

The reference might come as a surprise to some, but true Potter fans know: Hermione totally has a muggle iPod and rocks out to Chamillionaire while she’s studying. It’s officially canon. But how does this stack up to Rowling’s past Twitter cheekiness? Let’s take a scientific look.

The infamous Westboro Baptist Church Tweet

The Potter series is all about anti-bigotry, so it’s no surprise that Rowling jumps into the arena whenever she sees fit. Not everyone does it with this much style, though. We’ll give it a 9 out of 10.

The Donald Tweet

This tweet is also bigotry-focused, though she managed to slip in a nice Potter reference. 8 out of 10.

The Serena Williams Tweet

Rowling also shuts down body shaming like a boss. We’ll give this one a 9 out of 10.

That time she told Neville to put clothes on

Rowling demonstrates her motherly feelings whenever former Potter actors do risqué photoshoots: We’re going with 8 out of 10.

That time she Tweeted about Inverse and yours truly

Because this made our day and — let’s be honest — year, it’s a 10 out of 10.

That time she made fun of someone and her own books simultaneously

This one also gets a 10 out of 10 for hilarity and her willingness not to take herself too seriously.

Which brings us, at last, to her latest: the Chamillionaire pun.

To use our scientific evaluation method, this hits all the sweet spots: self-mockery, nifty and unexpected references, and serving a sloppy sandwich to someone who deserves it. It ranks a 10 out of 10, much like Harry did in the First Task of the Triwizard Tournament.

With Fantastic Beasts around the corner set to top even the original Potter films, there’s no telling what the future could bring in Rowling Twitter sass.
