During TennoCon 2019, there was a panel from Cameron Rogers and Ryan Mole titled "Building Fortuna's Society". As part of this panel, an image was shown with a list of Solaris slang along with their definitions (the list was later posted to Cam Rogers' Twitter). As these slang terms are essential to understanding many of the dialogue lines from Solaris characters, this list and its transcription are reproduced here.
