Secert sound. what they have in common. I KNOW WHAT IT IS. But i need help with 1 thing.?

I have found out what outside, kevin costner, petey pablo, and soap have in common. But the problem is i cant get through to call. so i am willing to let someone know what the sound is, and if you can get through we can split the money. if your willing to do that, and your the first to answer back then i can set it up. i live in greensboro, nc, so i only ask that you are from greensboro as well.
