To lurk is to creep around, hide out, and wait to attack. Your team’s strategy for winning capture the flag might be to lurk in the bushes for an hour until the opposing side thinks you gave up and went home.
The verb lurk means to move furtively or sneak around, usually while you wait to pounce. Tigers lurk through the jungle, stalking their prey, and creepy characters are always lurking in the shadows in horror movies. Perhaps that’s why you’ll often hear people describe not-so-safe places by saying that danger lurks at every turn. Other words for lurk include creep, prowl, and snoop.
