A while ago I started using Socks and Caps as shorthand for social anarchists and anarcho-capitalists respectively. But then I drifted away from it, mainly because there seemed to be no useful article-of-clothing shorthand for us lefty individualist types in the middle.

But there is! Mack (or Mac, but Id prefer to avoid the association with either computers or hamburgers) is an abbreviation for an article of clothing a Mac(k)intosh raincoat and also works as an abbreviation for FMAC, itself an acronym for Kevin Carsons phrase free-market anti-capitalist.
Okay, its a bit less intuitive than Sock or Cap but on the other hand it has the advantage that macks are generally worn between socks and caps, which is just where we Macks generally find ourselves because, yknow, were the vital center, while Socks and Caps are bewildered deviationists.
Also, its more embarrassing to be caught wearing only socks, or only a cap, than to be caught wearing only a mack thus reinforcing our dialectical superiority. Plus Zerzanites can denounce all three groups, since Zerzanites dont approve of clothing of any kind.
