When two, sitting, people are flirting by touching knees usually under a table. Similar to footsie but is better done while sitting side by side or kitty corner, and is less likely to cause outbursts of laughter. Also the recipient often wonders if the kneesier is doing it on purpose.
Q: Was that creep playing kneesies with you too?
A: Yes, my knee willnever feel the same.
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 fatenough for me to put it in the elbowgina, but the kneegina was a perfect fit!
