An art movement and/or form that is based solely on arbitrary, or unplanned, usually reluctant, actions to create artwork. This style spans many mediums, and surfaces.
This can also be person who does such art work, or constitutes behave in other aspects.
It can sometimes, but rarely, be used to generalize a sub-culture. Members of this culture are almost always found in New York City, you cannot classify them by dress style, for they may prefer to wear skinny, regular, or baggy fit jeans, sometimes, slacks, or Khakis. They do of course dress odd, accessorized with vests, cardigans, fedoras, scarves, odd glasses, unpopular shoes (Vans, Onitsuka, Gravis, Ipath, or vintage/rare sneaker, like old Nikes, and at some extremes members of this culture would wear shoes found in dumpsters, or hanging from telephone wires). Usually members make effort to break common stereotypes. The ideology are very vast and open-minded, but usually include ideas of, Equalism, Pacifism, Environmentalism, Bohemianism, and Freeganism/Meeganism.
Anna: Aren't you gonna take a shower?
Mike: Nah. Hopeful I'll take one if I eventually, magically, fall into the tub; or if the shower head found it's way to come to me.
Anna: So you stink, and you're not gonna move from that couch. Wow, how Rilwan of you.
John: Wow, my piece is due tomorrow for critique! Eh, I'll do it... If I get to it...
<next day, in studio class, John just finished his piece 2 minutes before class>
Student Critic 1: I like john's work because it seemed as if its free, carefree, breaking boundaries, as if it were done just 15 minutes before class...
Student Critic 2: It's good, because its so Rilwan-esque, it achieves near perfection, showing, a huge amount of effort in very little time, thus creating an improvised mastery...
Douchebag: I hate those kids, those Rilwans, they think they're so cool because they listen to metal, indie, and rap, and talk about Aesop Rock, Steve Aoki, Hadouken!, Trivium, Tokyo Police Club, and Minus the Bear all day... I don't even understand how they dress, one Rilwan is a Black guy in a pretty tight fitting outfit; black jeans, black v-neck, black canvas shoes, and a heather cardigan; meanwhile the other one is a Asian guy who is wearing regular fitting jeans, with a scarf, neon blue tee, and a red and black Flannel jacket, with disgusting retro Airwalks that he must found in the garbage.
