Geritol Generation
Basically it would be the 'older' generation of folks that rely on "Geritol" vitamins to get around and stay healthy. Also known as "Blue Hairs", they can be seen hanging around casino's - usually drunk, reeking of smoke, and screaming at the bands that they are "too loud, turn it down!"
Wow - it looks like the "Geritol Generation: beat us to the free buffet this afternoon!
