‘Sunbeam’ is an interesting one. Obviously an English word , however the meaning in Australian is unused crockery or cutlery. Now in England the word is (was) used to greet or address someone you know; generally in a friendly manner.
As in ‘ey up sunbeam how you doing, not seen you for a while’
However if you alter the intonation slightly it can also be used in a derogatory manner short of a strong cuss,
for example addressing someone that runs into your car ‘well done sunbeam, that wasn’t a very clever move was it’.
Very subtle. To confuse issues more there are many other words used similarly whilst greeting someone
example: ‘eh up duck’, ‘ nah den mate’, ‘good afternoon chappy’….
