Triple Dip (DDD)
A sex act in which the man penetrates all three orifices of a woman, in the worst order, meaning, he begins with the anus, then moves to the vagina, and finishes with oral sex.
In the pornographic film "Cunt of Red October," Marko Ramus finishes the 15 minute orgy scene by doing a Triple Dip (DDD) on Janice Ryan.
