You may not have met it Tim but I have certainly encountered it. And it is very off-putting for adult novices sometimes - I know when Stephen started riding again 5 or 6 years ago now he was mocked something rotten by hoards of small girls when he wasn't familiar with some of the horsey terms and felt awkward asking, he had me to translate as I was brought up on good pny club jargon but I have met other adult novices who felt very intimidated by it. Obviously that is partly a yard issue, but while I like some of the traditions I see nothing wrong with a bit of plain English too.
