lilspeak 

A dialect of written slang used by littles, mostly on chat and message boards. Spelling is extremely phonetic, reflects child-like speech impediments, and may be otherwise incorrect. Grammar is extremely child-like. Comments frequently reflect child-like miscomprehension of others' comments.

Come to think of it, that describes ebonics, too.
