Each week we bring you a new, unique Aussie word.

rum 'un

in Tasmania, an eccentric person, a character or wag, a cheeky person or scallywag. Formerly common all over the country but now restricted principally to Tasmania. Also spelt rumun and rumin. From rum `odd' and 'un `one'. Aussie slang from the 1890s, but ultimately from British dialect.
