The backstory: My school has a dress code and, among other things, the students are not permitted to wear blue jeans. Leggings are also prohibited. But, as this recent conversation with a student demonstrates, not everyone agrees about what these words mean.
Me: You know that blue jeans aren't in dress code, right?
Student J: Yes. These aren't blue jeans. They're jeggings.
Me: By which you mean blue jean leggings? Leggings aren't allowed either.
Student J: They aren't jeans and they aren't leggings. They're jeggings.
Me: You should go to law school.
This is a battle I'm doomed to lose.
