I think "the young" have a jargon all their own, and we ancients are not supposed to understand it.
Only discovered recently where 'dissing' came from – abbreviation of disrespecting – as in "Are you dissing my drawing?" and other daft stuff. (How can you disrespect a drawing? )
I think there are two languages running concurrently, and I don't understand one of them. I have a 22 year old niece, she is well-spoken and privately educated, yet she writes phrases on facebook that I can only guess at - and know that I must be wrong.
This is this morning's offering.
'Oh dear John I hope you have a good "sauce" of a adventure!'
