1.
Usually a person who
a)Smokes a BUNCH of weed
b)Wears V-Neck's
c)Constantly at little corner cafe's

But there are two different types.
The rich ones always wear american apparel, jersey knit v-necks. They are usually really huge jerks, and listen to the more "upscale" indie music. Nobody likes them, and everyone calls them emo. Usually gay/bi, or at least everyone thinks so. They're obsessed with their macbook, and making sure they look "fashionable." Which usually means that you copy everyone else. And you read nylon, even though you're a boy.

The average ones just wear whatever they can find at the salvation army. Sometimes they accessorize with hemp baja jackets.
They are usually the trendy ones that everyone like. They don't shop at hot topic, and they definitely aren't gay. They just live up life with cappucinos, and awesome marijuana. Sometimes they have dreads, but that becomes too hippy-ish, so in order to be a real krill, cut those dreads!

PS
Most Krill are men. It isn't cool to be a girl krill.
