What you do if bored on the internet. Involves watching the side-bar adverts on the email site, and then hitting the REFRESH or INBOX buttons to see a different ad. Akin to TV channel-surfing.
"Dude I was so bored yesterday waiting for that girl to email me back that I did some email surfing to pass the time."
"Did you see that identity theft one?"
"Yeah, like TWENTY times!"
