Alas, I must disagree with my associates. An earlier archaic and authentic definition of "gorilla biscuits", along with fender benders
and ape wafers
, referred to any of the brightly colored palette of barbiturates; reds, blues, and yellows,* readily available in the sixties (1967, not some fucking 1987 Grateful Dead concert). It slipped official notice that these drugs caused more mayhem and death than the Vietnam War (except, of course, for the Vietnamese).
Anyhow, I remember being struck at the time by the witty repartee in the example below, overheard in some dingy quasi-hip tenement decades before the band was named and some poseur managed to confuse up and down.
*Optional Text - Weird Ramblings: Now that I think of it, these are the very colors of the Wonder Bread Balloons... Coincidence? That's what they want you to believe! What? Never heard of Wonder Bread? That's because I'm getting so fucking old, and that's why Nembutal is enjoying a new popularity among my peer group, that little ace in the hole you want to keep within easy reach when the time comes for the compassionate healthcare providers to put you on life support and torture your ass for five or ten years until your estate is exhausted. No thanks, sonny; pass the goof-balls and a pint of Ballerina Vodka.
