Definition of a Blog...

...Courtesy of CBS's NCIS, or to be more accurate, courtesy of a rerun of it on USA.

A Co-Ed explains to Agent Gibbs (Mark Harmon) what a blog is, in this exchange from a 2006 episode entitled "Twisted Sister":

Co-Ed: ...she trashed me in her blog.

Gibbs (perpelexed): Blog?

Co-Ed: Yeah.

Gibbs (no less perplexed): What's a blog?

Co-Ed: It's a, b-blog, you know.

Gibbs (very matter-of-factly): No, I don't know.

Co-Ed: It's s-something losers put online so that everyone can read...

So there you have it.

**And no, I don't watch NCIS, I'm not that cool. It just happened to be playing in the background as I was blogging of all things.
