In the Australian vernacular, a bludger is a word used across all classes to describe a layabout or otherwise lazy or slothful person.

"That Tommy of yours is a bit of a bludger, isn't he mate?"
"Well mate, he reckon's he's goin' to the University of Bondi next year"

The worst form of bludger is the dole bludger, a largely mythical invention of conservative politics who supposedly lives the life of Riley (an easy life) on Government handouts.

Shortened, the word bludge means to "take it easy" or to take without moral right.

""Jeez, that history class was a bludge!"

"Can I bludge a ciggie off you mate?
