Clinton handshake
A friendly method by which teenage girls express their interest in socializing with male counterparts; involves placing the male penis inside the female's pie hole, and then bobbing up and down with a sucking motion. This "handshake" is decidedly not sex, nor sexual in content or motivation, as defined and testified to by former U.S. President Bill Clinton. Also, the means by which married, middle-aged men show their appreciation to junior, entry-level, female subordinates for outstanding "service".
"You may now perform another Clinton handshake under my desk, while I make a phone call, if you promise not to tell the First Lady."
