Unintentional references to real world entities...

[prizzley]

I've avoided mentioning the adam's apple in my book because I couldn't work out what to call it in a world with no Adam. I never thought of smeerp-lump ...

I just made sure everyone wore high-necked clothing, so no one saw it.

I think this is a brilliant thread. Unintentional references or references about things that shouldn't be known to people living in a fiction world poses a great threat to the consistency and believability of the work. There are great examples as how it can be worked around as done in The Death Gate Cycle.
