Omegle.com

I just discovered this site today and it is probably the greatest way to waste time and you should all try it. It's a random chat site. You click a button and you're chatting with a stranger. There are no sign ups or anything involved, just straight to business. Sure, half of the people there are dudes looking for someone to cyber with, but they're probably the most fun to mess with. I was actually chatting with a stranger that said they were 18, a girl, and from Korea. Of course I think they're full of shit and then make up some of my own dumb shit to call their bluff. Turns out she really was a student and I had to disconnect from the chat because chatting with a high school girl is sort of creepy.
