Off the point

When I lived in the Bronx we called it stoop ball. Or, when we played it against the wedge of a wall and the sidewalk, we would call it off the point. (Counterintuitive? Do I misremember?) When we moved to the suburbs, where there were no stoops and where walls didn't meet sidewalks, but lawns, we played in the street and of course it was curb ball. And my brother and I played our own special variation of the game, called roof ball or off the roof. (You can imagine.)

Streetplay.
