Noun (n) - The sort of English you come across occasionally that is incomprehensible.
Generally, this form of English is spoken by "tweens" or pre-teens who pretend they're much older than they really are and have access to Facebook, MySpace, Twitter, or other similar social networking websites.
Your brain may short circuit when reading said English and your soul may die a little (or a lot. Symptoms vary.)
