1. Verb, passive, intransitive: For a ball to be pocketed. "The 8 ball fell early, so the game was over quickly."
2. Noun: The curved edge cut into the table bed at which the hole of the pocket actually begins inside the pocket jaws . The fall may be a sheer drop, as on tournament-standard snooker tables, or have a beveled, down-sloping rim, as on pool tables. A ball is, of course, much more likely to hang when there is no bevel. How far into the pocket the fall begins is one factor that determines "pocket speed " or difficulty.
