Not so, Douglas Harper, you are being silly. No word can mean the exact opposite of what it is intended to express. Words transfer information between a minimum of two human beings and any validation is only subject to the sucessful transfer of the intended meaning.

But irregardlessly, most double negatives are perceived by the ear as intensifiers or emphatics, especially here in the South where when you say "I don't want no mo grits" it means that you really doesn't want any more grits at the moment.
