when you are receiving a harmless reacharound and just before you nut, they jam a thumb in yr land down under and they scream good day mate

A regular reacharound except you're both hanging upside down. Sometimes called the Auzzie Roundabout. It doesn't have to be homosexual, you can do this with a man or woman and sometimes you can switch roles, but role switching would involve a strap-on depending on the gender of those involved.
"The Australian reacharound is a very intimate position and is recommended towards married couples."
