Aborigine

A sexual act of a musical nature.

Step one…… you start by going down on a female. Step two…. You double arm under her legs, lifting her ass in the air.
Step three…. You start playing her cheeks like a drum.
Final step…. Blow down on her ass like a didgeridoo, and wait to see what noises she makes

I went on a tinder date last night, we had a few drinks and next thing I know I was going “Aborigine” on her ass.
