Origin
The term is most-likely a reference to the Rubicon river, which in the time of the Roman Empire marked the boarded between Cisapline Gaul and Italy proper. Crossing the river with an army, as Julius Caesar did in 49 B.C., was illegal by Roman law and is commonly seen as the "point-of-no-return" for Caesar's revolution. As such, a "rubicon" can be used idiomatically as any strict dividing line or point-of-no-return.
