I said to an attractive young lady that kept folding at the hips while skiing as she went by -
"Ali - If you keep sticking your a$$ out, we'll keep looking at it!"
For the record, it wasn't a class. It was a friend from work that a few of us were coaching after beer league. Nothing motivates a young lady to stand tall while skiing like knowing three middle aged men are staring at her butt.
She's probably told all her friends about you...and not in a positive fashion. I have a daughter who gets a lot of comments from a few of my older ski buddies. I can assure you her comments to me are NOT flattering about them.
