What to do for my 15th birthday.

Okay, first things first. I am not hispanic or even partly hispanic, so quince is out of the question.
Second, my dad is a cheap a*** who wont let me go out to dinner with my friends for my birthday.
Next, I dont wanna have like a cutesy little princess...

girly party like that.
Then, I am having a few guys come, so I need something for them to be interested too.
And, I don't feel to partyish. I am going to a party a day before my birthday and I am really tired of hanging out in my house with food and music for hours.
Lastly I want to have about 10-15 people over and it to be semi-formal, but again, jerk of a dad so I am unknown.

I know I am sounding really picky about this but I wanna have fun. And I NEED HELP!

If you want a really easy solution which me and my mates do sometimes is a joint party with someone? that way you can volunteer someone elses house if your lucky.
If you want something at your house you could have a themed party? im not tlking princess and princes. Like a mexican meal kinda night guys love dressing up like idiots. Also if you really dont want to spend much money at all get all your mates to chip in like £5 or $5 cant tell if your american :P. That way it will cost you very little and unless your mates are real cheap they will give you money just never ask them to bring food themselves because that always goes bad!
