Definition of Roll

A natural is an easy shot requiring no side spin. A shot is said to be natural if it does not require adjustments, such as a cut angle, side spin, or unusual force. A natural bank shot, for example, is one in which simply shooting straight into the object ball at medium speed and with no spin will send the object ball directly into the target pocket on the other side of the table.

Feel generally refers to that elusive quality that makes one cue feel special or superior to another. In essence, it is the cumulative effect of all of a cues characteristics, including weight, shaft diameter, balance, grip material, length, etc. It can vary greatly from one player to another. A cue that feels great to one player does not necessarily fell good to another.

Two or more object balls that are touching or are close together.

Hitting the object ball with not enough of a cut angle; hitting the object ball too full or "fat". It is a well-known maxim that overcutting is preferable to undercutting. See also professional side of the pocket.

Also double-century break. In English billiards, a break of 200-299 points (i.e. double a century). Larger multi-centuries are regularly achieved. Rare in amateur play, triple centuries are routine, and quadruples not uncommon at World Professional Billiards Championships; 2007 winner Mike Russell shot four triples in the final round alone, while of sixteen competitors, three shot quadruple centuries (one once, one twice, and Russell three times). Quintuple centuries are rare even at the professional level, with only the 494 shot by nine-time World Champion Russell (who has more such titles than any other player in history as of 2007) coming close in that event. World Champion Geet Sethi holds the world record, at a duodectuple century (and then some) of 1276 consecutive points."

Powdered chalk housed in a cube. This chalk is rubbed into the tip of your cue to help with grip between the tip of the cue and the cue ball. This is more important to use if you are using a medium or hard tip, as opposed to a soft tip, which already provides some good grip. As a warning when purchasing a type of chalk, there is much debate over which chalk offers the best friction, so you best do your research!

A common way to keep track of games won when playing for small money is to use a coin that is placed under the rail next to the diamonds on the rail. The center diamond at the head of the table is taken as zero, and each diamond from that is considered to be one game. To go 'around the world' is to beat your opponent so badly that the coin travels all the way around the diamonds on the table.

Also money-added. Said of a tournament in which the pot of money to pay out to the winner(s) contains sponsor monies in addition to competitor entry fees. Often used as an adjective: "a money-added event".
