1. When playing the wooden dice and number game "Klackers," "Klack" is to score a zero in your round, which is the best score you can get. 2. "Klack" is onomatopoeia, the sound that the numbers in the Klacker game make when they are pulled down, thus "Klacking" against the wood.
If you get a zero you Klack!
