A person who fails to accept commonly-accepted laws of reality, such as gravity and the police. Often associated with heavy LSD consumption, excessive use of Day-Glo paint, and frequent momirovs.
Without warning, the kesey leapt through the crack in the sky, sputtering multicolored paint upon the confounded constables below.

Leader of the famed Merry Pranksters of the 60s psychedelic movement and main character in Tom Wolfe's Electric Kool-Aid Acid Test.
"Kesey walked into the room and everyone stood still."
by Stephen Mandel May 29, 2005
The author of "One Flew Over the Cuckoo's Nest." Major influence in psychedelic drug use on the west coast such as Timothy Leary was on the east. He and his band of Merry Pranksters experimented with drugs such as LSD and cannabis beginning in the early sixties, predating much of the later era hype. In I believe 1964, they undertook a cross-country road trip in a psychedelic, day-glo, hand-painted old school bus. All along the way, they "turned on" many people to the mind-expanding effects of LSD. They lived communally at Kesey's cabin in La Honda, and hosted parties called Acid Tests where the house band, an early incarnation of the Grateful Dead, played. Here, they served "Electric Kool-Aid," which was Kool-Aid spiked with acid. in short, Ken Kesey is one of my idols.
Ken Kesey and his band of Merry Pranksters are described in detail in Tom Wolfe's novel, "The Electric Kool-Aid Acid Test."

Pronounced: /key'zee/
(Kesey) can easily be defined as a person/group of people, situation, place, thing or idea that is either suspicious, shady, annoying, likely to fuck you over, fuck you up or make a joke out of you,

Derivative from the infamous group "Ken Kesey and the mery pranksters," a squad of crusty bus hippies who fallowed the dead around along with the rainbow family and were complete shady assholes. Their escapades included: dosing unsuspecting festival goers with lsd without their concent, stealing, ruthlessly clowning on anyone they can and generally all the negative aspects of what one would call "Wook" behavior.
"Bro that dude at the party with the insane clown posse shirt on tried to sell me fake weed"

"Bro that jugglalo was kesey af"
"That whole party was hella kesey fam"
