I used to play something called superdudes religiously and it was a great place for college students to compete as well as a great family enviroment for kids to play around. Its a kinda comic book site where you create your own id as a superhero and battle other players. You play games to win points and get new attacks.
as much as i would love to be on superdudes more i really am stressed for time. Most often you can find me on another site http://www.darkwars.org/index.php?a=click&id=26019
feel free to check it out if you want something else to do or if you want to join on. This is a site alot less involved than superdudes but it is also very social with just as many clans and groups you can join. Invite your friends and you can all climb the rungs together and compete in a nice friendly manner trying to steal eachothers hard stolen, i mean earned, money. Its a great place to go play and chat without being obligated to spend alot of time at it.
If you are just looking for something fun to do and enjoy the whole hacker slacker experience, or you just like to laugh at your friends who do, then heres a web comic you might like. If you want to check it out they are always posting great online games and such that will entertain anyone for hours. I promise you will be anything but bored looking at the strange if not useless information and merchandise on their think geek page. You will find things that you wish you had, or more importantly will make you laugh that someone actually uses it. Which they do i assure you. Where else can you find a miniture grill that will plug right into your usb. Anyway, here are a few ideas to sculpt your web browsing. I hope I have been at least somewhat helpful.
