In relation to the rawdog, "inserting your penis into a women's orifice without a condom", this term references the all time great Ron Jeremy. In other words, if rawdogging is good, then rondogging is better.
Last night I was rondogging my slampiece and I tried to stick it in her butt. She said, "Isn't that a bit presumptuous?" So I said, "Isn't presumptuous a big word for a nine year old?"
