Holy cow!!! Look at what's on Faldage's link: The Snopes were a family of characters weaved throughout the works of Pulitzer Prize-winning American writer William Faulkner. When David Mikkelson, creator of snopes.com, first came onto the Internet in the late 1980s, he worried even back in those relatively uncrowded days that no one would remember yet another David. He was thus inspired to adopt a nom-de-Net, selecting one that honored those fictional Faulknerian characters, and began signing his newsgroups posts as "snopes."

And, and,...I am fairly a-tremble with excitement:
Glurge is a term specific to snopes.com, coined in 1998. Already in its short lifespan it has reached across the Internet and has appeared in the print media a number of times, and it may well soon make the final breakthrough by appearing in dictionaries as a bona fide entry. The word was invented by Patricia Chapin, a member of the urban legends discussion mailing list run in conjunction with this site. At a loss for words to describe the retching sensation this then-unnamed category of stories subjected her to, she fashioned a word that simultaneously named the genre and described its effect.
Oh, how VERY satisfying it is to know exactly how a word came into being! That's what I want to know about ALL of them!!!

I thought this was interesting also: Ostension is a folkloric term for the process of unwittingly acting out or mimicking the greater part (if not the entirety) of an urban legend that is already part of the body of lore. More simply, if the events described in an urban legend which had been around since 1950 actually did indeed spontaneously play out in real life in 1992, that would be an example of ostension.
Is this related to ostentation?
