Jedi Thumb

In an attempt to engage in anal sex with a female who is not initially interested in the activity, you approach your sexual partner while in the doggy style position and slowly work your thumb over her asshole in a calm, clock-wise and stroking motion. You slowly increase the pressure to instigate a pleasurable sensation, during vaginal intercourse, to influence her into accepting your penis in her rectum.

Friend: "Dude, I can't believe you got to take a ride on her Hershey Highway! I thought your girlfriend was scared of anal?!"

You: "She was; until I used my Jedi Thumb on her...'you want to let it in there'".

Friend: "Epic sir."
