Don't tell me you have never heard of "pussy/pussie" in your social environment 😁
I thought it somewhat fits there because as an anglicism, it is a softer word than most german alternatives , but yet it is also obscene. So it might fit a character who can become kinky at a given time, but without it actually being a dominant characteristic of them.
For instance, "Mumu" is a "Verniedlichung" , if you get what i mean, so it best fits to characters which are childish or cute and do not prefer to show their dirty side or maybe who are even innocent. So those were my thoughts behind it...sometimes I also just chose it by feeling, though.
What would be your suggestion at the part with Linnea and how do you perceive Nene as a character though? I'm curious.
