I would partner with a historian friend of mine to write it. I'm good with dialog, and he could keep it authentic. Write a rough draft like a normal script, then go back and fine tune all the dialog to surfer bro without changing anything else.

All the Nordic women would speak in Valley Girl.

There are a lot of interesting discussions around the use of food in movies. Even ones that aren't directly about food.

Regular food intake is critical for our survival so it makes sense that it takes a large social role.

As a general rule, making and sharing food is considered "good".

• "Everybody eats when they come to my house." - Cab Calloway
• "You can get anything you want, at Alice's restaurant." - Arlo Guthrie

Taking and consuming food is "bad".

• "Get in my belly!" - Fat Bastard
• "Mind if I have some of your tasty beverage to wash this down with?" - Jules

The exception is when food is offered. In that case, graciously accepting the food is also good.

• ET and Sloth (from Goonies) accept the candy.
