(sometimeshyphenated) A longstanding children's game in which multiple players stand behind a throwing line and each takes a turn throwing a stone (sometimes called a "duck") at a target rock (sometimes called the "drake") that is guarded by another player, such that when a player's thrown stone dislodges the target rock all the players run to retrieve their thrown stones, while the guard replaces the target and then attempts to tag a player before he or she can return to the throwing line. If the guard successfully tags a player, then the guard and player swap roles.
[B]asketball . . . is . . . cobbled together out of irreconcilable parts: James Naismith invented it, out of desperation, with a peach basket and a football and the rules of an old children’s game called Duck on a Rock.
