Examples:
That's cat - i.e. it's not very good.
Couple of personal favourites from the 80's
Eeeezy Snapper! - i.e. steady on, young foolish person
This is the hat - i.e. this is great, or pretty good.
Can no longer remember whether it was good to be one of the "Kingsmen" or bad
There was also a period of "Eeeezy, soft hands" another "steady on, young foolish person"
I'm sure more will make an appearance
