What about the "stink palm".........wipe your hand down your sweaty butt crack then transfer all that "energy" to someone you really aren't that keen on.
I once got former Liberal premier Jeff Kennett with a massive Stink palm. It was the high point of my political life. Somehow though, I think he knew I was Stink palming him.........but he just smiled took it and moved to the next potential voter........Kennett was a pro!
