Really don't think you have to worry until she starts asking for you to "pass the ******* butter"

Seriously, if she happens to use the expression again a gentle correction is most likely in order.

How did you keep from busting out laughing???

When I was a kid my sister and I were riding with my father and mother in the car. My Dad asked my sister to do something and she didn't move quite fast enough for my fathers satisfaction, she was asked a second time and responded, "Hold on, don't cream your jeans". This was before seat belts, my father hit the brakes so hard I thought my mother was going to go through the windshield.

Well, my sister never used that expression again. Can't beat good parochial school education.
