Definition: A set of entire games won by a single player in a row, a "five pack" would be five games won without a miss (term used most frequently when the rules stipulate the winning player retains the opening break); also, a synonym for a "cluster" of balls huddled together on the table.
Also Known As: Cluster
Examples:
Fast Eddie threw me a four pack in a race to six, and put the match all but out of reach.
