Language is decided by the collective anyway. If someone is able to convey his or her meaning, then he or she has effectively "mastered" the language.

Words are being added, taken away, and/or changed constantly. Try singing "Blow Boys, Blow" at a bar sometime, and you'll know what I'm talking about.

Words are just words. They convey meaning though. If the audience understands thier meaning, then I don't see a problem.
