On another thread someone used the expression 'taking the mick'. And I thought, 'I used to hear that all the time when I was a kid. But I rarely do now.'
So I started to think of others that my dad used but my kids don't.
'Having a kip' or 'I was akip'.
'Yikes' (My daughter says I'm the only non-cartoon that says 'yikes'.)
'Swinging the lead'
'Bunking off'. (Daughter: 'Never heard that. Sounds rude')
'Going Dutch' (Daughter. 'Nope. No idea. Is that rude too?')
'Haven't the foggiest.'
These were all in use in London fifty years ago. Maybe they were always regional.
