Can someone explain why my models hips are doing this after subsurf modifier? I am very new to blender and I decided to make a man. However when I apply a subsurf modifier, my mans hips look strange. Can anyone explain why??

Thanks.
Looks like you have some extra geometry in the hip area. Try using Remove Doubles or fixing it manually.
