A person who is just "there." Nobody really knows why, other than they show up and don't say a word. Possible reasons for this could be:
-They don't know what to say
-They are pretending to have friends
-They are trying to scare you
-They are there just to be seen with you, as if they have some kind of relationship with you.
Person 1: Who's that?
Person 2: The lurker. He shows up everyday, just ignore him.

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.
Anthony: That Jessica is such a lurker.
Trey: Yeah, she's always around.

Marcus: She just pops up unnoticed.

Antonio: Yeah, seriously!

A turd that refuses to be flushed, hangs out just barely visible below the escape hatch
Dude, I pinched this massive loaf, but after flushing 3 times, I still noticed a lurker.

Lurkers lurk. This lurking may exist in the form of excessive monitoring and creating of PT threads, checking out other people's myspaces without the intention of leaving a comment or message, or hitting on/trying to get with someone. Most people are a lurker sometimes, but you aren't truly a lurker until PT or myspace is used everytime you see a computer, or you're creepy (possibly old) and hit on mad girls.
I was lurking on PT instead of writing my paper!

Oh my god he is such a lurker!

Wish I was lurker... Wish I was on myspace...

One who creeps relentlessly, usually used to refer to males who will contact a female more than 3 times a day through Facebook, Myspace, Text, Calling, and Instant messaging. The female must not be interested.

Powerful Zerg unit, upgraded from Hydralisks costing 100 Vespene Gas and 50 Minerals. Effective on ground units only, utilized best with stacking at entrance way to base. Low hp/armor but when burrowed, will not appear on opponent's screen unless observer/overlord is present.
