What to do for a 14 year old girls' birthday party?

I'm turnin' 14 at the very end of August ( 27th ). School starts Sepetember 1st and I'm goin' into High School. I'm from a very small town in Connecticut and I wanna do somthin' fun. I'm deffently unique.... I'm not very girly at all and I have very little friends. I love music and sports but I just don't know what to do. Also I hate alot of attention. All I know is my mom's gonna make me a pink and black 'Green Day' cake. If you could give me good ideas that would really help, thanks!
