Another year,older woman and younger man sex video man another flurry of Twitter-based badassery from everyone's favourite wizard Queen.

J.K. Rowling doesn't normally take any nonsense from anyone on social media. In the past she's hit out at the Daily Mail, Rupert Murdoch, and the Westboro Baptist Church, to name just a few.

This year, though, her wand has predominately been aimed at one source in particular: Donald Trump. Also Donald Trump's political allies, Donald Trump's family, and just generally anyone associated with Donald Trump.

From cutting sarcasm to all-out assault on cartoon frogs, here are some of Rowling's most brutal Twitter burns of 2017.
