Yes, I remember the term with a smile...a few questions come to mind, such as
- What's "light" petting?
- Can you pet yourself and it's okay or does that have to involve other people?
- What's the exact approximation when it becomes petting, is it one touches, two?
And yes, these are questions I actually asked back in the day, which of course, still reminds me of the looks of complete horror, coughing, and trying to change the topic...
Oh, and I still thinking "petting" is about as sensual as it comes before intercourse.
