<noun> A term used to describe a person, usually male who "lurks" - appears out of random corners, happens to "bump into you" or always seems to be at the "right place at the right time" aka - where you are. A lurker tends to be the last person who left you a message in your inbox or sent you a series of pointless and annoying texts right after passing by you (it still remains a question how he got your number in the first place), and it is extremely rare for any girl to have the desire to respond to these pitiful cries for attention.

When you do have a face-to-face encounter with a lurker, conversation usually consists of really awkward tidbits that never develop into anything remotely meaningful or could also take on the form of an interview session, during which the lurker asks you a series of questions to which he clearly knows the answers to, as made evident through his history of extensive stalking. Encounters with lurkers leave all women with an incredibly overwhelming sense of awkward displeasure.

Tip: Women -Avoid lurkers at all costs ; Men - Never become a lurker.
"Yeah I thought he was cool, but he turned out to be a lurker"

"That kid is such a lurker, it's disgusting."

A lurker is someone who always just seems to be there, no matter where it is.

You always expect them to be there, because they pop up out of no where.

A lurker will often try and play it off as a joke when you confront them, but it's not a joke.
