For the benefit of non Australasians, "Snagger" is Australian slang for sausage, taken from the BBQ (Barby).
Slightly OT...we use the word "snag/s" to refer to sausages, but isn't it "sanger"? Or is that just where I hang out?
Or is a sanger a Sandwich??
Sometimes theres just too bloody much slang for an "ocker sheila" to remember!
