Forum Thread: Best Party Themes for 11-17 years old

Now this is when it gets tricky. Is there a party theme that is cool enough for tweens and teens? I think back to this age and I don't think I would have been so bold as to have a themed birthday party--maybe a holiday party could be themed, but that was about it for me. What do you think? Is there a "cool" party themed for this age group?
