Soldiers in the Roman Legions used to shave down pig knuckles into the shapes of cubes, and toss them onto their inverted shields as a form of entertainment while in camp. Hence we get the term "to roll the bones". We do know that the game we know today as "craps" came to the United States from Europe.

The inside walls of the table are covered with a serrated egg-carton like foam, designed to make the dice bounce around to assure randomness. Each throw of the dice is called a "roll". Players take turn rolling the dice, clockwise around the table, and the player rolling at any given time is called the "shooter". When a new shooter is given the dice, his or her first roll is called the ""Come Out"" roll. This begins a new series of rolls by that shooter and lasts for as long as that shooter continues to make winning rolls.
