What it means
To lurk is to hang around online, read everything, watch every post or story, and never pop up with a like, reply, or comment. You're there, soaking up the whole digital soap opera, just moving in silent mode.
Usage examples
"I do not post much, I just lurk."
"She lurks in the group chat but never says a word."
"I was in the Discord the whole time, just lurking and clocking everyone's drama."
"Don't mind me, I'm only lurking on Insta tonight, no chat, no likes, just vibes."
Where it comes from
Lurk is an older English verb that meant to stay hidden, hang back, or wait out of sight. Online, it kept that same sneaky-shadow energy and got picked up for people who read forums, chats, and feeds without posting or interacting.
