“Guaranteed Good Chat” or GCC. GGC is shorthand when I’m making an introduction by email or text. A GGC is bright and delightful. Well-informed but not haughty.
It takes work to be a GGC. You have to be a talented listener and conversationalist. You have to brim with high and positive energy. You have to be emotionally accessible so we feel as if we’re being heard.
There are many ways to describe someone extraordinary but GGC does just fine.
