To hide or remain out of sight, waiting for an opportunity; or to be present in a hidden or subtle way.
From Middle English 'lurken,' of uncertain origin but possibly related to Old Norse 'lurka.' The word has meant to lie in wait or hide since at least the 1400s.
On the internet, 'lurking' became such a common behavior that we had to name it—thousands of people read forums and social media without ever posting, which completely changed how we understand online communities!
