Aha! I am immune to tvtropes.org, having chronically overdosed on people talking about media I have never seen and never will see, during my university career as the token "physicist in a roomful of arts students". Take that!
(Not to mention conversations where somebody describes something using a word from one book that I have never read, I say I have never read the book they quite from and do they mean square/heavily ornamented/irritating like swallowing a tablet the wrong way round/a bit like a llama, and they say "sort of, but not quite, more like [the same damn word]". Yes but maybe relate it to something in REAL LIFE. Anyway. Pet peeve.)
