Shitty Australian

This is when you are naked from the waist down wearing super thick boots. You then stand on the toilet to take a shit because you are afraid that an australian sized spider will crawl up and bite you on the ass.
"Sara saw a video online of a giant spider swimming in the toilet after some Australian flushed. Now she only takes a shitty australian when she has to poop."

Australian Unicorn

A rare phenomenon that happens when someone pees outside on the coldest of days. The name is derived from the idea that the urine could freeze into an icicle which would resemble a horn. Therefore, that person would be a unicorn down-under or an Australian unicorn.
Bryton: Dude, what's taking so long?
Matt: It froze up on me! Ahh, it's painful!
Bryton: Haha, you're totally an Australian unicorn now!!
Andy: I can relate, that happened to me once too. Ouch!
