learning a certain language to communicate to believers and the religious

[Thumpalumpacus]

Hello to you all in this forum. I had a discussion with a user in a thread I made from the old aint no god forum that I was apart of many years ago who goes by or went by the name Terrene where she told me there is a language I could learn to talk with believer's and/or the religious without offending their beleifs Or I would think without having them get hostile. If I remember right she said it was much harder to do then getting into a debate with them. I want to learn this language but I don't recall what the name of the language is. If anyone here knows The name of the language I am talking about, I would greatly appreciate it if you could tell me. Terrene posted a picture in that thread describing the language or to give an example of the language where there were 2 sock puppets talking to each other. This may give a clue to what the language is called.   

@Terrene 
If you ever see this, what was the name of the language you were talking about called?

I would imagine that would be the language of courtesy.
