When two or more object balls are frozen or nearly frozen , such that cue -ball contact with one object ball , without the necessity of great accuracy, will almost certainly pocket an intended object ball in the cluster . The most common form of dead arrangements are the dead combination or dead combo (a combination shot in which contact with the first object ball will pocket another one), and the dead kiss , in which contact with the first object ball will pocket it off of another one. See also wired .
