"salut"

I'm finally in French 101, after a while of on-again, off-again self study.

Today in class our professor told us that the greeting "Salut!," if pronounced the wrong way, means something along the lines of "son of a bitch." What word or phrase did she mean? I don't want to call anybody a son of a bitch (immediately, anyway), but I am curious now and I don't know her well enough to come right out and ask her..

Grand merci!
