(Referencing the books up to Persepolis Rising) Something I genuinely enjoy thinking about is the mentioning of non-descriptive obscene gestures, or when a character says something obscene. Especially when the Belter's functional hand signals are so descriptive, and character dialogue can be quite colourful (Avasarala being the prime example). I imagine if obscene hand gestures were the same as they are now, would Martian's don the middle finger to match their aggression? Would mischievous Belters make the jerk motion? Think back to the gesture of biting your thumb at someone from Romeo & Juliet, how insulting it was then, how humorous it is now. What do obscene gestures look and sound like hundreds of years from now?
