Another campaigner is Jo Macaldo, a dancer, who recently posted a photograph of a male passenger with his legs comfortably spread. "Guys, why do you do the #man-spread?" she wrote. "Is it painful to keep your knees together? I'm really curious."
The man-spreading crisis has become so problematic that some female journalists went as far as to try to go into character as a male passenger and emulate their habits, better to try and understand the issue.
Gabrielle Moss spent a weekend travelling with her legs parted like a man and wrote about it for Bustle.Com.
"The man who takes up multiple seats on public transit with his splayed-out legs inspires all sorts of questions among his fellow riders," she wrote. "Is the leg-spreader exercising his male privilege, or, as some defenders would have you believe, merely attending to the unique spatial requirements of his balls?"
Nobody from the Metropolitan Transportation Authority was immediately available for comment. But Paul Fleuranges, a spokesman, told the New York Times that staff had spent no small amount of time trying to ensure they got the correct tone for the advertisements aware their efforts could be open to parody or mocking: "I had them add the dude part," he said, "because I think 'Dude, really?'"
