I don't know why someone's kid would be looking at your RoadID.
As far as your mom... a few years ago my parents were visiting for the holidays and I dropped something in the kitchen and broke it, and the same word that's being abbreviated up there just FLEW out of my mouth.
My mom's an elementary school teacher, and that prompted a good discussion about how she keeps words from flying out of her mouth in similar situations.Your mom has probably heard that word before, too.
