It is not a single word, and you probably first heard it in 2017, but – despite this – "Me Too" has been named Macquarie Dictionary’s word of the year for 2018.
The phrase beat out 15 shortlisted words for the top spot, including "deepfake", Scandinavian wellness trend "hygge" and "BDE" (that's "big dick energy", Twitter's favourite description of both Ariana Grande and Anthony Boudain).
"Me Too" was first coined by US activist Tarana Burke in 2006, who used it to create a campaign encouraging women of colour to share their stories of sexual abuse on now defunct social media network, MySpace.
The term – and movement – was then popularised by a tweet by US actress Alyssa Milano, following the publication of sexual assault allegations against Harvey Weinstein by the New York Times in 2017. Me Too, often used in hashtag form ("#MeToo"), came to be associated with subsequent allegations made against other powerful figures across entertainment, sport and politics.
