The name given to the act of going back and forth between licking the vagina and asshole on a female.
Guy 1: Yo man I heard you gave your lady a chocolate tuna!

Guy 2: Yeah man I did. She loved it when I went back and forth licking her pussy and asshole.

Guy 1: I'm going to have to try that on my woman tonight!
