They're three simple words that could make a huge difference to a woman feeling uncomfortable on the street: "You OK, sis?"
Feminist writer Feminista Jones started the social media campaign as a way to bring awareness (and hopefully help put an end) to street harassment.
"One day I shared this story about how I intervened when a young mother was being harassed on the street," Jones writes on her site. "During this conversation, I called on everyone to just try it once... try to intervene when someone is being harassed, but in a way that won’t exacerbate the situation."
Jones detailed the experience on her Twitter account in June: She described how the young mom "had a large butt and tight dress so men stared." A man selling CDs allegedly approached the mom, who was pushing a stroller, and grabbed her arm. Jones said the woman brushed him off and kept walking, but he continued to pursue her. That's when she sped up and decided to intervene, asking the mom a simple question: "You OK, sis?"
"Street harassment is a global problem. Period," writes Jones, who says she has been passionate about the topic for years. On her site, she shares a number of resources and platforms that she hopes will help people better understand the issue.
Women (and men) have since been using the hashtag to share their own thoughts and experiences:
"Many people said they were unsure of what to do or if they could do anything but now they feel empowered to do more," Jones writes. "The tag is universal and everyone can weigh in. We welcome the support and want to continue to build with other movements to fight street harassment."
