Lifted from the comments:

A feminist educator in the United Kingdom is making a point not to step aside when men walk in her direction, playing what she refers to as “patriarchy chicken.” […] “A few days ago, I was having a bad morning: my train tickets were expensive, my train was delayed, and my coffee was cold,” [Dr Charlotte] Riley wrote. “But I cheered myself up by playing a game on my commute. The game is called Patriarchy Chicken, and the rules are simple: do not move out of the way for men.” If that sounds like something that would be ungentlemanly conduct if perpetrated by a man, you would be correct in your assessment.

Dr Riley, you’ll note, is a grown woman.

Our feminist lecturer’s New Statesman article, in which she elaborates on Patriarchy Chicken and its allegedly empowering effects, can be found here. We’re told, somewhat implausibly, “It’s important to note that Patriarchy Chicken isn’t about anger.” When not applauding herself for repeatedly and deliberately colliding with male commuters, Dr Riley informs us that “war and peace can only be understood through gender.” 

Also, open thread.
