I’m sure you all know what a double negative is — two negative words that together mean a positive.  For example, if you say “I don’t have nothing in my hand” means you must be holding something.  I have heard of intellectuals (I think that’s the appropriate description) who like to string negatives together to see who can figure out the correct final negative-or-positive meaning.

Now could the reverse be true?  Could two positives actually mean a negative?   This is considerably more difficult.  I have only heard of one expression that would fit in this category (and sorry, I don’t remember where I first heard it).  It’s the sarcastic “Yea, right!”
