It is a long-refuted
chauvinist claim that when women say "No", they really mean "Yes". What women
really say when they actually mean "Yes" but are too
inhibited to admit it is "Nah", often following a surprising degree of
openness. As in:
Alice: Our sex life is so boring! What I would really like, Frank, is if you tied
me up, gagged me and spanked me to exhaustion!
Bob: Really?
Alice: Nah ..
Be careful, though, "Nah" is also used in a derogatory fashion, meaning "not a chance", as in:
Bob: I will be your willing sex slave, mistress! Whatever you command, I will do
without hesitation!
Alice (looks into his pants): With a three-inch-tool? Nah ..
NAH also happens to be the airport code for Naha, Indonesia.
