A custom during the reign of Caligula as Roman Emperor. When meeting a friend, whoever was ranked lower had to bend over and the higher ranked would fist-bump the end of the other person's larger intestine (colon). Very popular among the higher ranks.

Popular today among young men and fans of the movie Caligula
Gaius: Hey Longinus
Longinus: Oh... hey
Gaius: You know the drill, bend over.
Longinus: Do I have to?
Gaius: What?? You are refusing to shake the hand of your superior???
Longinus: No....
....
Gaius: There, was that so hard?
Longinus: : |
Gaius: Well, you know thats how we Romans shake hands. A "Roman Handshake" if you will
