On each front paw Koala's have two thumbs to help them climb on to trees and grab food. So the ultimate thumbs up to someone is to make a C with your thumb and finger. Its like a double thumbs up!
My mate Amanda hooked up with a hottie so i made the Koala thumbs up sign as she was walking off so she knew i was heaps impresssed!

The act of fucking a partner upside down. Reminiscent of a primitive koala bear. The position allows for comedy humour and should be repeated multiple times in one sitting. Many Australian-born males are taught such a position at an ealry age when they are sent to compulsory bush school.
Antoin: Gee Leroy, I pounded that woman like a Koala bear.
Leroy: Oh, upside down and multiple times.
Antoin: Yeah, just like we were taught at Bush school.
Leroy: Oh, upside down and multiple times.
Antoin: Yeah, just like we were taught at Bush school.
