This is exactly what my mother would say in a scenerio around the lines of
Me: Hey mom, how are you feeling this fine evening
Mom: Good sweetie, are you sure you feel okay
Me: Me pfffssssss, I'm great but I've got to tell you something
Mom: Okay, what?
Me: I have a boyfriend, he is cute and nice and ge is also popular....
Mom: What the bleep did you just say!!!!!! You are too young, I will take you to the mental hospital and I will go personally to your school and kill him!!!!!

This is exactly what would happen
