I need something that can help me tell if a house guest has communist brainworms, but doesn't signal anything to the uninfected. I was thinking something like a print of one of the Diego Rivera murals where Lenin is lurking in the background. I need some more ideas. It could be music, some choice phrases, some prominently displayed literature, etc. But it has to only be meaningful or interesting to the already initiated.
Edit: My wife is pretty sure that a normal American does not know what Lenin looks like. However, a portrait of Lenin won't work as a shiboleth if I'm asked to explain who he is.
the word based.
The words fully automated luxury gay.....
the word zoinked
the act death grips
(some of these are false shiboleths to throw off the :fedposting: )
