A lolcat is the halfway point between dentist office posters and Linux geeks. Pictures of animals (usually cats) doing funny, cute or silly things with captions over the top either describing a possible scenario for the cat or providing words purported to be spoken by the cat. As cats are new at speaking English, it would stand to reason that their spelling and grammar is also terrible. This mishmash of unlikely bedfellows makes for some good laughs.
