the Three-Fingered Bus Driver

An obscure sexual maneuver popularized in Russia, in which the vagina and anus are simultaneously penetrated, with a thumb and two fingers, respectively. The rectum is then pushed outwards into the cervix, where it is rotated by the two fingers.

"Darryl gave you the three-fingered bus driver?"
"Yeah. It was the most horrifying experience of my life. After that we went to Olive Garden."
