Back-alley, In-the-skip style of sex. Often used as a
lighter, funnier way of joking about gang-rape. When said in a deep
throaty voice can give the perfect
impression of a randy tramp.
Example 1.
Dirty Mike: "Oi, Unclean Pete, getcho ass over here. I see a young man in need of a good ol' Jonnying. Cover me boys, Ima goin' in!"
Example 2.
Wife:
Are you okay sweetheart?"
Husband: Well, they sure gave me a roight Jonnying!"
