Earholes

While on a class fieldtrip with Hunter yesterday, we sat next to a couple of girls and another mom as we ate our sack lunches.  The girls started to talk about their upcoming birthdays.
Hunter says, "Oh yeah, did you know that Jenna is getting her earholes for her birthday?"
::::I'm in a stupor, not knowing what to say or how to respond::::
"You mean ears pierced?"
"What does that mean"
"Earholes, it means earholes."
