N.C.A (National Cougar Association) - A club you're in if you're too old to be sexy but still try

A club you're in if you're too old to be sexy but still try to act like you are and nobody believes you.

'She's in the N. C. A. and still wears a minidress to the grocery store.'

'He called me a cougar. I said, 'I'm not a cougar, I'm a N. C. A. member.'

'I joined the N. C. A. because I'm too old for love but not too old for drama.'
