The next step after kanoodling. All sexual activity with the exception of actual intercourse. Includes above and below waist activity such as all oral pleasuring. Sometimes shenanigans are necessary in order to get to the finagling stage.
After a lovely evening of kanoodling in front of the fire, we had crazy shenanigans but refrained from f*cking.
