A sick day from work or school, especially one taken without a valid medical reason.
A sausage, probably from a Scots dialect term (also “snag) meaning a morsel or light meal. Other Australian words for sausage include “snarler” and “snork.”

Someone who’s stupefied or out of it. A mullet (fish) that’s just been landed is typically goggle-eyed and open-mouthed.
