My friend has been talking about suicide very often and I really think hes going to do it…He says hes ugly, unpopular, and theres just no reason to live…he’s tried to hang himself but his parents found him…i really dont know what to do, im going to call and tell his parents but i dont know if its the right thing to to do…plz sum1 help!!

Yes…call his parents.
He may hate you for doing that at the moment, but he’ll thank you later.

If you care about him, then you should do whatever it takes to stop him doing it. I remember having to spend 5 hours one night takling a friend in college out of suicide. It was one of the most difficult things I’ve ever had to do. Would you like some advice for such a talk?
