Okay kiddo, so a skintern is someone who works as an intern at a ski resort.
It's kind of like when you help out your teacher in class, but instead of a classroom, you're working at a really cool place where people go to ski and have fun in the snow.
As a skintern, you might help with things like organizing equipment, showing people where to go, or even helping out in the cafeteria.
It can be hard work, but it's also a lot of fun because you get to be outside in the snow and see all the different people who come to visit. And who knows, maybe one day you'll become a really good skier and get to work at the ski resort full-time!
