The process of having sexual intercourse while utilizing a strap-on dildo affixed to one's chin - otherwise known as a chindo or chin-do.
Dude, I was having chintercourse with my chick last night. Chintercourse is so much more fun than regular intercourse - I get such a better view of her meat curtains!
