#EleNão, which means #NotHim, is a women-led movement against the far-right frontrunner presidential candidate, Jair Bolsonaro.
The movement started in opposition to Bolsonaro's long history of sexist, racist and homophobic comments.
In 2003, he told a lawmaker that she wasn't worthy of being raped. The video of the incident has more than 3 million views on YouTube.
He then argued in 2015 that men and women don't deserve the same salaries because women get pregnant.
With four sons and a daughter, he joked that he had a daughter out of a "moment of weakness."
He has also said that he would rather a son die in an accident than turn out to be gay.
He also made racist comments against Brazil's black and indigenous populations.
