I may have sung "Goody Goody yum yum" a few times as a child.
RIP Bill Oddie
Yes, but as an adult, when would it come up in normal conversation, other than maybe 'goodies and baddies (which I also use ironically)?
There are other words I have not used since I was about 10, like 'horrid' and 'cross' (as in, you'll be very cross) and 'wuss'.
I know those last three tend to be more English things anyway (I think).
Anyway, back to Accygate...
