Expanded Glossary from the book - Illustrated Principles of Pool and ...

coefficient of restitution (COR): technical term used to quantify the “rail rebound efficiency” or
the impact efficiency between two balls.
collision-induced english: same as “cut-induced spin.”
collision-induced spin: same as “cut-induced spin.”
collision-induced throw: same as “cut-induced throw.”
combination shot: a shot where the cue ball hits an object ball into another to pocket the
second ball.
combo: same as a “combination shot.”
come into the line of a shot: have the CB approach the OB along the aiming line, offering the
largest margin for error with position.
connect the dots: a “roadmap” layout; or the run-out of a “roadmap” pattern.
contact point: the point of contact between the cue ball and the object ball at impact.
COF: coefficient of friction.
COP: center of percussion.
COR: coefficient of restitution.
Coriolis: famous French mathematician and physicist who wrote a book on billiards physics.
Corner-5 System: a formula-based diamond system for aiming three-rail kick shots.
corner hooked: when the cue ball is left in the jaws of a pocket with the path to an object ball
blocked by one of the pocket points.
corporation: two or more people who pool their money together in betting on a person in a
match or Calcutta.
cosmo: a “roadmap” layout.
counterman: pool-hall worker who rents tables and sometimes serves as a “middle man” to set
up gambling matches.
crawfish: To back away or backtrack quickly when approached or revealed, like a crayfish when
startled (e.g., when a “nit” backs away from a bet after his wager gets called; or when a person
tries to quickly “fill a hole” he has already “dug” for himself).
cross corner: a bank shot off a long rail into a corner pocket, where the cue ball crosses the line
of the shot.
cross side: a bank shot off a long rail into a side pocket, where the cue ball crosses the line of
the shot.
crutch: slang term for “mechanical bridge.”
CTE: center-to-edge, referring to the line of aim going through the center of the cue ball and the
edge of the object ball, which creates a ½-ball hit. This line of aim is used as a reference or
point-of-departure in some aiming and alignment systems.
cue: the tapered wooden implement used to strike the cue ball.
