fall like dominoes Meaning, Definition & Usage

Definitions
  1. . To fall sequentially, as when one object in a line, by falling against the next object, causes it in turn to fall, and that second object causes a third to fall, etc.; the process can be repeated an indefinite number of times. Derived from an entertainment using dominoes arranged in a row, each standing on edge and therefore easily knocked over; when the first is made to fall against the next, it starts a sequence which ends when all have fallen. For amusement, people have arranged such sequences involving thousands of dominoes, arrayed in fanciful patterns.
