The new term is manslamming:
there’s a helpful new word in the man-as-prefix lexicon. Meet “manslamming,” which New York magazine’s Jessica Roy uses to describe the behavior that is, on a sidewalk, refusing to yield to a fellow pedestrian such that a collision inevitably ensues. More broadly, Roy says, it’s “the sidewalk M.O. of men who remain apparently oblivious to the personal space of those around them.” It is (usually) done by men, (usually) at the expense of women. It is (usually) done unconsciously.
Awful behavior. I instinctively give way and get out of the way when I'm in public. I abhor the possibility of causing injury to someone else. That's more Minnesota Nice than it is anything else. Maybe I picked it up in the Army, which is where you have to get along with people or find yourself in peril. Who knows?
