What song is this that's always advertised Who want it hoo hoo?

Hi there's this song from either the 70's or 80's that I'm trying 2 find. But i don't know the name of it or who it is by. It kind of goes who want it uh hoo hoo hoo do you really want it now baby. You would hear it on the rock stations on the radio all the time. What song is this can anybody identify it for me?
