Anal sex. Basically another way of saying "bumping uglies."
While I was in jail for a few months, I had the biggest laugh of the time when I went to the restroom one evening and saw two prison guards dunkin' donuts with each other in a shower stall.

The act of placing both of your testicles into a womans anus during the act of copulation. When done correctly, a delightful pop will be heard when they are suddenly pulled out with a quick upward motion.
"So, I was dunkin donuts into this cheerleader the other night..."
