Surfers wear wet suits when the water is cold. I've been known to wear board shorts, and any type of swimming trunk. Also sometimes, surfers will wear nothing when they are taking a shower. Every once in a while I like to wear a spring suit.
When surfers are NOT in the water, they tend to wear clothes that cover up their bodies, since it is illegal to walk around naked. I have many hardcore surfer friends who wear t-shirts and jeans. Also going around barefoot is not a good idea, so my hardcore surfer friends wear shoes. Shoes protect the feet.
Also they say stuff like "top of the morning" "i'll be gosh darned!" and "your on the trolley!"
Why are you asking dumb questions?
