an Aussie abbreviation for "Are you sure you don't?". Usually only used by people with a university degree and later stolen by extremely good looking people.
good looking person 1 '' do you want a beer?''
good looking person 2 '"no thanks mate"
good looking person 1 "sure not?"
or
Lawyer "want a piece of cake?"
good looking person "no it will ruin my good looks"
lawyer "sure not?"
good looking person "your not a good looking person"
