An elderly person who is a proficient user of the Internet. My grandmother has become a real silver surfer since we got her new computer hooked up to the Internet. She even keeps in touch with her friends on social media!

One who quickly switches between channels on a TV, as while looking for a program to watch. Hey, channel surfer, can you slow down so I can actually see what's on?

Someone who rides a skateboard, especially as a means of transportation rather than to do tricks. This town is full of sidewalk surfers zipping by on their way to class or work. I used to be a sidewalk surfer when I was in college, but after breaking my ankle I never got back on a board again.
