A website which depicts grammatically inept, socialist cats that suck time out of anyone who is foolish enough to look. Most likely created by crazy cat ladies... or Hitler, either way they're frickin' sweeet!!

An interweb sensation, it is the term for silly pictures of cats with subtitles. They are generally characterized by poor spelling and grammar, and for unknown reasons, tend to mention cheese burgers often.

One reason for this may be that the (rumored) first lolcat ever said "I can has Cheezburger?"
"hey! Did you see the lol catz with the Persian kitten?"

"The one that said 'you eated my cheezburger'? Yeah, it was funny but what an ugly kitten"
