A selfie "down under" AKA a picture of your junk.
I accidentally tweeted my Australian selfie and it ruined my political career!

A self-made picture of yourself, but "down under"; specifically referring to the vagina.
I asked my good fried to take a picture of her pussy with her smartphone and send it to me, and she said "oh, you want an Australian Selfie".
