I’ve witnessed manspreading on the subway, mostly. Once I asked a young man to stop doing it–I and the woman on the other side of him had each lost half our seat–and he launched into a tirade of personal insults, implying that I was too fat to fit into my seat, which I can assure you was NOT the case. I said, “It’s a matter of common courtesy” to which he replied, “In NOO YAWK???” What a boor.
