The insults caught on tape – from “Whores!”, to “Hey, dolls!” – come thick and fast. Six months later, the footage is still being shared on social media networks, and has even become a regular feature at feminist conferences.

The video is entitled ‘Las Morras confront their aggressors’ and has already been watched more than one million times. It was filmed using a GoPro hidden in the backpack of an accomplice who keeps pace ahead of the women. It shows Las Morras wearing skirts and tight-fitting tops as they walk through the streets of the Mexican capital.

The video begins with a short prelude, in which the women explain, “We are four young women who live in Mexico City. Like other women, we suffer harassment and abuse whenever we walk through the streets. We’ve decided to ask the aggressors whether they have anything to say.”

Barely 30 seconds into the video, several people begin whistling and shouting dozens of insults, calling them “whores”, with one asking, “Are you going to a funeral?” Some men stop to stare intently at the women, smiling all the while.

And instead of taking the abuse, the women stop and call out the men shouting at them, demanding, “What is it? Do you have something to say to me?” Unsurprisingly, most of the harassers are taken aback at being addressed and are silent in response. The women go on, “Right, if you have nothing to say to me, don’t speak to me. Ok?” or, “Don’t talk to me in the street if you don’t know me!”

The women also say that they were followed by a man when they were on their way to buy water. According to them, he waited for them at the entrance to the shop, then masturbated in front of them – he can be seen in the video.
