A slang word used by hippies, tree-huggers, and a select few unnaturally awesome human beings, to describe an event (usually an outdoor adventure) in the most preposterous, beastly, epic way.
CARDIGAN can also be broken down to describe 73.9% of the average hippie's vocabulary:
C-ool
A-wesome
R-adical
D-ope
I-cey
G-narly
A-ce
N-autical
I'm sure none of these kids at the ski hill have any idea how totally Cardigan our day is going...
The bush style a woman sports when she leaves the pubes alongside her labia in their natural state, which gives her vulva the appearance of a open cardigan sweater.
While Jillian did trim the length of her pubes to keep her bush from getting too wild, she didn't shape it and left her lips hairy, so her pussy looked like a brown cardigan.
