The Lurker 

n. The guy who hangs out by the dumpster in the 7-11 parking lot. He doesn't really ever do anything; he just looks like he's about to. The Lurker has a well groomed molestache and still listens to Snow and Vanilla Ice. Also seen at NASCAR events.

Be careful dude, I saw The Lurker over there last week.

Facebook lurker 

Someone that passively trawls Facebook, but doesnt leave a Facebook footprint by writing on walls, commenting or liking things. Facebook lurkers love the book, but seek to create a facade that they're never on it

Hey check out Warrick, he's always looking at Facebook, but never doing anything on it. He's such a Facebook Lurker

left lane lurker 

An operator of a privately or commercially owned automobile (typically a Toyota Prius) who has gone full-retard and operates said automobile at a speed well under the designated speed limit in the left-hand lane of a multi-lane roadway when other roadway lanes are clear and free of traffic -or- other roadway lanes are loosely occupied by other motorists traversing at a similar speed.

I swear to God, if this left lane lurker doesn't merge over I'm going to fucking ram his Prius off I-40.

hard lurker 

someone who does as little work as possible yet still acts as if they are the hardest working person on the planet. close relative of the spotlight ranger.

Sgt Frank is a hard lurker, he is always talking about how much work he is doing, but no one knows what he actually does or ever hears of him accomplisching anything at all.
