Me Too movement

"Me Too" (or "#MeToo", with local alternatives in other languages) is a viral two-word hashtag used on social media in October 2017 to reject sexual assault and harassment, in the wake of sexual misconduct allegations against movie producer and executive Harvey Weinstein. 
The phrase, long used in this sense by social activist Tarana Burke, was popularized by actress Alyssa Milano, who encouraged women to tweet it to publish their experience to reject the widespread nature of misogynistic behavior. In the manosphere, some people described the Me Too movement as misandric.
Since then, millions of people have used the hashtag to come forward with their experiences, including many celebrities.
Impact.
Tens of thousands of women replied to Milano's tweet, including:
Some men, such as actors Terry Crews and James Van Der Beek, have responded to the hashtag with their own experiences of harassment and abuse.
On November 16, 2017, US Senator Kirsten Gillibrand of New York specifically referred to "the 'Me Too' Movement" when asked about allegations of sexual misconduct by politicians such as President Donald Trump, former President Bill Clinton, Senator Al Franken of Minnesota, and Roy Moore.
The hashtag has been used in at least 85 countries.
