Bodacious 90’s — ‘As If!’

There is a lot of good that has come out of the 90's. Music, movies and slang! What is your favorite slang from the 90's?I have many but, the best ones that comes to my mind right now is 'as if!' In other words, 'do you really think that I am stupid enough to do that' or 'do you really think I am stupid to fall for that!' Cher does it best in Clueless!
