Starting here (http://anarchistnews.org/comment/217471#comment-217471), there begins a conversation about this word and what it means. I have some opinions, but I am also afraid I am being a little too prescriptivist; maybe the word has drifted, since it's initial coining by Aragorn! some months ago, to mean a different thing.
I would certainly be interested in hearing what others think the word means when they see others using it, or what they mean by it themselves.
I will start by saying that I understand the word as a perspective on the world that is centred on struggle (of a particular type: mass or mass-ish and understandable as anarchist) and which assumes that more struggle is more good, as well as some attitudes that follow from this perspective, such as judging everything based on its utility to the struggle (without even necessarily having a very coherent metric for this evaluation) and feeling inadequate in one's self for failing to struggle (or inversely, feeling very smug about oneself for how much struggle one is doing).
I see it as a bad thing.
