A person, often stereotyped as being from a third-world country, who cannot read or write correctly.

Though it has technically nothing to do with the internet, it is used here (on the internet) as a stereotype for people who use a shortened version of english known as chatspeak or leet. Many people judge chatspeakers before they even get to know each other, calling said chatspeaker, "stupid" (etc.) because they're not willing to find out if the person is really stupid or if they do know english. Perhaps they might be from a different country? Chatspeak is often used as an alternative for correct english because people are simply too lazy, not stupid, to type in correct english. Though it may not be a faster way to type for chatspeak haters, it is for chatspeakers. Others are unaware that they're being discriminated against, so they keep using chatspeak. Some people use it for humor and are still hated for it. Perhaps the haters should learn it themselves.

Chingy,that crappy lil pop rapper who can't spell!

A class of a large, and growing, number of people, particularly children, who are unable to read or write.
Illiteracy is beginning to take over the United States of America. After seeing all those Hooked On Phonics advertisements, I have concluded that our country is becoming more and more filled with illiterate brats who deserve a good slapping upside the head.
Apparently, illiteracy is so common that there is evidence of illiteracy in China (the world's #2 superpower). Illiterate children is said to be the result of lazy, irresponsible parents, therefore resulting in much lack of education. It's times like this that, although education sucks (because of schools and how boring they are and having to put up with punk-ass bitches with cruel attitudes), it is very necessary.

If you had a kid who couldn't read a word, wouldn't you like to slap him upside the head too?

(adjective) to not be able to read or write in a specific language. Used loosely, it can describe someone who is just an incredibly sloppy speller.

People who cannot read or write

A moron with the approximate education of a fly at best.

A person who is unable to read or write. Basically, an unintelligent person who has the approximate education of a second grade English student, if not worse.

A user on a website who lacks the proper literacy skills needed to communicate properly. They spell words with "shorthand" spelling, known as chatspeak. Words are spelled with singly letters, number replace letters in some words.

These people claim that they type that way because it's quicker & easier, which shows tell-tale signs of lazyness. They accuse people who type properly of being elitists.
