Sounds to me like this kid needs a good ol' fashioned hide-tanning. Repeatedly. She's 8, not 2. She knows exactly what she's saying, and if it were me, I'd wash her mouth out with a bar of Dial and see how she feels after that. That is totally inexcusable, and Kelli, you should not have to deal with it. Someone needs to straighten her out real fast before she grows up with that foul mouth.
