Uncouth Louts: Larrikins, Mug Lairs and Yahoos

Older generations of Australians generally didn't approve of waste, showoffs and vulgar flamboyance.

Virtues such as temperance, modesty, perseverance and constraint were necessary due to factors such as economic depression, wars, hardship and lack of birth control.

During the convict era, young men associated with jauntily wearing fashionable hats made from the cabbage tree palm (Livistona australis) were labelled Cabbage Tree Mobs.

In Melbourne, the word larrikin became popular after police sergeant John Staunton described youths to the magistrate in his Galway brogue, larking about in the street ('larrr a kin').

Ned Kelly, in his 1879 Jerilderie letter, wrote: "It takes eight or eleven of the biggest mud crushers in Melbourne to take one poor little half-starved larrakin [sic] to a watch house".

The British-English term "lout" was first recorded in 1596 in the writing of James Dalrymple.

Mug lair also seems to be derived from the British slang word lairy (or leery), meaning "knowingly conceited" for a flashily, showy, rude and socially inappropriate young person (usually male).

In the 1950s, there was a new group of louts. Males were called bodgies, and the females were called widgies. Dressing in a similar way to the British Rocker, an article in the Perth Sunday Times of 1952 claimed that "......bodgies originated in America, but it's only in Australia where they're called bodgies. The word is a term that originated in Sydney, to describe anything "lairy".

A hoon, is generally a term of derision for a young bloke who drives too fast. The word originated from rhyming slang, "silver spoon", for someone who lived off immoral earnings.

Crude, loud, or stupid, the word yahoo was coined by Jonathan Swift in "Gulliver's Travels", for an imaginary race of brutish creatures.
