The term "blarg" is thrown around a lot these days, but what does it really mean? I utter the word quite a bit and even I wasn't really sure. So, I decided to hit up the urbandictionary to figure this tricky devil of word out.
My favored definition:
"Blarg is an expression that can be traced to its root words, blah and argh. Blah may be a shortened form of the word blasé meaning uninterested, or unconcerned. It is often used to express boredom. Argh is an expression commonly used in online chat and video games to express frustration.
The meaning of the expression blarg combines the defintions of the root words; frustrated boredom or disinterest."
Pretty apt. Anyway, so as I was reading this, I realized that I totally fall into a state of uninterested, unconcerned boredom which is sometimes even coupled with frustratration. When this happens, I usually want to go bitch about my situation via a blog post. But, at that point, I'm not blogging - I'm blarging.
I did a google image search on blarging and this little guy came up. I think some dude drew him or something. Does he not scream blarg?

Blargnor the Blargmonster!
