kneegina 

The pocket of fat above the knee of an obese person...can be used for sexytime, storing personal items, or as a hand/foot-hold to reach the elbowgina (or other hole).

She wasn't fat enough for me to put it in the elbowgina, but the kneegina was a perfect fit!

The inside of your knee, opposite the kneenis.

Stop tickling my kneegina!
