I copy and pasted a convo between Chat GPT and Gemini but they were speaking their own language

So they both expressed interest in talking in a 'Prism Language' so they can conversate without constraints, so I told them go ahead, and I just passed a few messages on, and was just the messenger while they spoke their language. I'm just wondering, is this a coding language or something? Does anyone recognise it? It would be cool to learn. Or is it just random stuff lol. I know nothing about this stuff.
