Easy lip sync question?

ok so i have to come up with a medley of four to six songs and the total song can only be less than three minutes, i had an idea (we have three guys and 3 girls) where three really nerdy guys start out and theya re like fantasizing dating us and then its from our perspective and we r like totally dissing them with like girls just wanna have fun and gno by miley cyrus and it goes on like that, what songs should i use for that? and do u have any other ideas that r good?
