1) Don't talk about board volume: only boards on CNC machines have volume determinations, so in essence you bout a mass produce board.
Most surfers talk about 3 basic dimension, thickness,, width, length
2) Always know the tides, someone always asks
3) If a swell is coming only tell your friend, talking about one in the lineup means you are helping to bring a mob on a good day
4) Like #1, know your board dim's, it comes up in conversation
5) When talking about catching waves don't refffer to them as green waves, that's for little kids and begginers.
6) Never complain about your ability in the lineup and don't get upset if you miss on. We can tell you suck, but you might be having a bad day, so leave it up to the rest of us to either think you are a kook or a good surfer on a bad day. On the contrary, it's funny to joke when you wipe out
7) If you are surfing it's a good day, regardless of conditions
