So, I'd be pretty irritated about this if I didn't find the whole thing so amusing.
djwong posted about this recently, but I'm going to repost the link for those of you who don't watch his blog.

Loltrek. Here's the backstory: people put silly captions on cute pictures of cats, and share them in chatrooms and on blogs. As the trend develops, it becomes an unwritten rule that the grammar and/or spelling in the captions is bad. Not just that, but bad in a very specific and predictable way. These image macros, dubbed lolcats, ultimately spawn the creation of the star trek parody which is linked to above.
Remember how I said I would normally be irritated by this? Mainly I'm just irritated by l33t or anything that resembles it, and that includes intentionally bad grammar. What can I say -- I'm a virgo with a passing interest in linguistics. Anyway, I was fully prepared to be snide and snippity about this until I realized that some of these lolcats are hysterical. I say some because there's a lot of people making them and not all lols are created equal. In any case, it's harder than I've laughed in a good long time.
So, lolcats, and related lolmacros, I forgive you -- you may carry on your insidious destruction of the English language. But don't let it get too far. The minute you stop being collectively funny, or the minute I see a bonafide l33t creep into one of your cat-tions [sic.], then I'm going straight back to my high horse of proper spelling and complete sentences.
But until then, I have no qualms in recommending this link:
