Yes, she's right but at least these are young people who use them that she's referring to so at the same time let's be rid of those Radio 4 cliches from people who should know better:
Overuse of the verb 'to target'
'It's not rocket science': just Newtonian mechanics with a variable mass
That 'Elephant in the Room'
'Blue Sky Thinking', whatever that means.
'Convenience Stores': are Sainsbury's inconvenient?
'Affordable Housing': what's the use of house that cannot be afforded
Etc etc
The majority of sports and business correspondents who seem to use standard phrase books.
