Here's an idea, how about you talk to your parents and ask them why they don't want to you have a party. The reason is probably because they don't want their house trashed, in which case you could suggest that you save up some money ad rent a warehouse or storage room for a night (great for parties as they are concrete floored so easy to wash when cleaning the next day, and they are often in rural areas so no noise control). If this isn't the reason, it could be that your parents don't want you hanging out with guys (lame reason but understandable at your age) or that they don't want to be responsible for somebody else's children. Whatever it is, let them know that you would like to have a party, and you are willing to pay for things yourself and let them see that you are really thinking this through.
If you're not allowed to have a party at your house, you don't do it. There's a reason why your parents say no. They don't want to have their house a mess or have things broken/lost/stolen. No matter how well you know these people, there's always a chance of each happening.
This is also an issue when it comes to doing it elsewhere. If you're throwing a party somewhere, YOU are held responsible for everything that happens. So.. unless your parents are okay with it, respect their wishes.
You parents don't want you to have a party in the first place, so why do it? *sigh*. You parents find out one way or another. No matter how sneaky you think you are. I would just wait until I can have a party with their permission , instead of sneaking behind their backs.
You must first rent somewhere to throw the party, and host it there. Try to get your parents to leave town or something to avoid being noticed. If they don't leave, say you are going to your friend's house or something and make sure that friends knows what you're doing.
Have just a few people over, don't tell too many people. keep it on the down low. And clean up very well! Also, don't be too loud. neighbors will call the popo if you are a disruption.
They always find out. Trust me.
