When you have sexual relations with a girl who you later find out has had sex with one of your friends or someone who you once knew. Then you are slapping-dicks with them. Much similar to sloppy-seconds.

Bob: I totally beat those cheeks last night.
Jimmy: Oh ya? Me too. A few weeks back.
Bob: Ah man! I was slapping-dicks with you.
Jimmy: Ya. Why?

A person of great evil from a galaxy far far away.
The first Seth Lord. George Lucas forgot to mention Dick Cheney was the first Seth Lord and the most evil. First name was changed from Darth to Dick, a dick is a dick no matter how you spell it.
