Reddit user VodkaPizza submitted the above photo, writing that their friend was on the E train this week when the alleged pervert pretended to read the paper while masturbating in front of them. You can see the gross, NSFW photo here. The uploader added, "so instead of being embarrassed about it, she stopped playing her video game and took a picture of it. He just shrugged like .. I didn't do anything." Classic subway perv technique.

The thread became an outlet for people to discuss their experiences with masturbating subway men, when another user chimed in about the perp above: "THIS GUY WAS ON #6 TRAIN UPTOWN AT 730 PM YESTERDAY!!!!! He was doing the same thing and the woman across from him screamed at him calling him a fucking!!!! He got off at Longwood Avenue in the Bronx."

We've come across more than our fair share of subway flashers, gropers and masturbators—they seem to be a fact of life here. But there are things you can do if you are a victim: to start, the MTA recommends promptly contacting an MTA employee or police officer (though that doesn't always work), but taking a clear picture and/or video with your cameraphone is a good step, too. As another user wrote in the Reddit thread, it's only a matter of time before the sign below is everywhere:
