What to do for my 14th birthday party?

Me and my 2 other bestest friends in the whole entire world want to have a super-dooper awesome combined birthday party. Joined obviously. We can do something awesome just us three or invite other people (if necessary) . Remember that the cost will be split between 3 families so anything goes [almost]. Please do not suggest a slumber party or makeovers or a movie night or themed parties. No links to gay websites either. And ps we live in vancouver. and pps make it awesome.
