Dingo stick

Best known as an object, most commonly a broken tree branch, used to fend off unruly dingos. Often required for personal protection on Fraser Island and other remote areas of Australia.

Term can also interchangeably be used to refer to a female fending off unwanted advances from Australian males, at events such as backyard bbqs and BnS balls. The dingo stick, in such circumstances, may take a less stick-like form, being an unattractive female friend, or grenade, if you will.
