samizdat

Used to refer to J. Incandenza's final film, "Infinite Jest" also known as the Entertainment, in David Foster Wallace's novel, Infinite Jest.

I've seen this word used a bit more widely. For example in reference to non-mainstream, usually lefty presses. Especially if they also rely on non-mainstream distribution such as pasting their screeds on lamp-posts and so on.

Dis? You want dis? It's the samizdat.

NOUN: 1a. The secret publication and distribution of government-banned literature in the former Soviet Union. b. The literature produced by this system. 2. An underground press.
ETYMOLOGY: Russian : sam, self; see sem-1 in Appendix I + izdatel'stvo, publishing house (from izdat', to publish, on the model of Gosizdat, State Publishing House ( iz, from, out of; see eghs in Appendix I + dat', to give; see d- in Appendix I).

I always thought it was a phonetic misspelling of "same as that" (unauthorized copies). Sadly, finding out that this is not the case doesn't make me like the word any more than I did before (1 - that rhymed, 2 - which was not at all).
