I've been hearing the term "man-spreading" used more and more. I'd like to propose another term:
Fem-blocking - This is when you're browsing in a store and a woman, completely self-absorbed, wedges herself between you and the item you were viewing. You can easily demonstrate this phenomenon by visiting the yogurt section of a grocery store. Any attempt to engage the offender is met with an overtly disingenuous "excuse me."
