It's a dark truth of the city: if you've lived in New York for more than a few years, and you're a woman, you have seen some guy flash you on the subway.
Usually the pervies do their thing and scurry away (except for this grand moment, when one was caught on camera) but HollabackNYC has a video of one woman who wouldn't let it go. "That's it!" she yells. "Oh you're getting fucking arrested. I'm not leaving your side. My plans are done for tonight."
