Party Ideas ?

Hello I am Having a party in a few days and i really badly need id eas... I dont want it to be very pricy at all, just a basic sleepover with some games... But as i am turning 15 years old, i dont want really kiddy games... Im not really mature and i am looking for something a lil more fun that just listening to music and chatting, but a lil more extreme than pass the parsel... Its a all girls sleepover, anyone who has any ideas for me please reply ASAP// the kind of games me anad my friends are into are like spotlight tiggy, egg throwing, murder in the dark... Ps ,... Also some things to put in party bags that doesnt cost loads but isnt just lipgloss and stuff ?? Thankyouuuu =]
