whack-a-mole

The "game" one has to play to quickly close the interstitial ads and other windows that pop-up on some commercial Web pages (especially porn sites). These pages will sometimes generate new windows every time you close a previous one, creating a situation similar to the action in the popular arcade game "Whack-a-Mole."
