Wrong again! There is no call in basketball called "over the back." What you described is a would be called a pushing foul.

If a player jumps straight up and keeps his/her arms straight, that's one thing. But to "wedge" in (push a bit) and to reach over the shoulders of the other player, making contact body to body, call it "a little lovin'" if you need to, but it should consistently be a foul.
