The practice known as "manspreading" has become an arrestable offense.

If you keep up on the New York City transit beat (and why wouldn't you), then you've probably heard about "manspreading" in recent months. It's nothing new; we just never had a catchy word to describe it before. Manspreading is when men (and sometimes women) spread their legs wide in their subway seat, taking up more than their fair share of room just to give their balls (if applicable) some space. It's definitely poor etiquette, and recently, it's become a metaphor for male entitlement in general. But it was never a crime before.
