The expression comes from an arcade game called Whac-A-Mole, first produced by Creative Engineering, Inc. in 1976. In the game, players use a mallet to hit mechanical moles that pop up randomly from holes. As soon as the player hits one mole, others appear elsewhere, creating a repetitive and frantic cycle that serves as a metaphor for modern task management and troubleshooting.
