The Cowra handshake

Whilst collecting horse semen...
You scoop a generous amount of cum up, and shake hands with your unexpecting victim, while shouting "Yeeee Hawww"

Person 1: "yo bro, I gave my mum the Cowra handshake yesterday"

Person 2: " whoa dude that's so standard of you"

Person 1: "Yeeeee Hawww"
