webCest 

Coined by Jeff Rowland, author of the Web-Comic OverCompensating, WebCest is defined as something that is "As bad as incest only it happens in Cyberspace"

From OverCompensating, August 2nd, 2005: "Webcest is that special feelin' you get when you're makin' love to your old lady and you're both dressed like giraffes! It's that feelin' you get when you got high-res, glossy printouts of tubgirl and goatse and you're all alone on a school bus."

Webcest 

Webcest describes actions of a sexual nature that have been made possible only by the internet. Something described as webcest should be disturbing to some large population, as incest is.

Webcest is that special feelin' you get when you're makin' love to your old lady and you're both dressed like giraffes!

It's that feelin' you get when you got high-res, glossy printouts of tub girl and goatse and you're all alone on a school bus.

Webcest is when you find dirty pictures of your ex-girlfriend on the internet and you print them out for later.

Webcest is when you realize that you're wanking off to a distant relative without knowing before.

Webcest is finding a porn site about a girl who looks like your exgirlfriend and bookmarking it.

Webcest is when you realize the fifteen-year-old you've been having cyber sex with is actually your niece.

You don't get STDs from Webcest, but you should.

Webcrastination 

The act of wasting enormous amounts of time aimlessly browsing the internet when one should be completing other, much more important tasks. It usually starts as a simple search or the checking of one's emails, and can last for multiple hours before the individual realizes it.

Most prevalent in college students.

This definition is on Urban Dictionary thanks to webcrastination.

Webmaster 

An outdated occupation, just like haberdasher, miliner or blacksmith.

In mediaeval times, every website had a Webmaster who used his mystical computing powers to keep all the flashing text, unreadable links and "under construction" signs safely in place.

These days people have found other ways of making websites work, and the last use of the word "webmaster" happened on Geocities some time in 2004.

When foreplay takes place via webcams prior to cybersex, leading to very fast webcasms (orgasming on webcam).

"All the online puzzle building led me to begin webcasm foreplay."

webcest 

Everything depraved, dirty, and otherwise morally outrageous that has become generally avaliable thanks to the internet.

Webcest is when you start putting your undergarments on the scanner and posting the pictures on pro-anorexia Livejournal communities.
