kooktalk
The language and greetings used by kooks when they meet, most frequently observed by non-kooks in beach carparks.
Kook 1: "Hey mate, what's it like?" Kook 2: "Man, there's some gnarly pounders breaking out there." Non-Kook: (at another non-kook) "That's some kooktalk right there, I haven't the foggiest what that means."
