Get the aussieboo mug.
To which a non australian has a large obsession with Australia moving their choice of words to an oversized amount of Aussie slang. The word is brought from the terms "koreaboo" and "weeaboo". An "aussieboo " is found using terms such as 'g'day mate', 'I'll throw a shrimp on the barbie', etc.
