wife's best friend, drain the dragon, siphon the python, ring the rattlesnake, unbutton the mutton, point Percy at the porcelain, shake hands with the unemployed: take a leak
Chunder, big spit, technicolour yawn, yodelling, laugh at the ground: vomit
As dry as a dead dingo's donger: in desperate need of a beer
One-eyed trouser snake, mutton dagger: penis
Bang like a dunny door, go off like an alarm clock: promiscuous female
Spear the bearded clam, knee-trembler, get dirty water off your chest: have sex
