I am on a few forums and struggle to communicate w/some people (not here).
Example: The Nonsensical Poster. This person posts utter nonsense. At times you wonder if the person is suffering from a severe episode of Disorganized Schizophrenia. At other times you wonder if the poster who seems to be an adult is really a 6-year-old. Her username is not a name but rather a sentence that seems to be an inside joke only she understands.
The signature is more bat guano babbling, with oD d *uS E* oF C aPs, **COLo r s and fO N T S !!1! You try to discern meaning in the pattern but there is none. They usually say something like, "I heart_____ tlf bff never ," but then it degrades into nonsense from there: " + = "
She usually posts what seem to be strongly held opinions but represent either a gross misunderstanding of the topic, drunk posting or pubescent hormonal rages. All posts talk about herself and end with lol and exclamation points.
I can remember a few of these types. One writes the same random word she made up in all caps between every 1-2 words in her sentences. Another writes LOL after every.single.thing. Example: "Hi everyone! LOL"
