kneegasm

The sensational vibe one receives when your knee cranium is stroked or rubbed. It is a tingly feeling much like an orgasm.In some cases this may be pleasurable, or if it is a more sinister kneegasm, it could turn out quite wrong! Best not to experience this in public, but to have a "friend" stroke you in the privacy of your own home.

Pronounced (cuh-nee-gasm)
(n.) A spasm in the knee area

The feeling, after a long or particularly difficult shift at work, when you finally get to sit down, and your joints release a wave of pleasure or satisfaction similar to that of an orgasm, most notably the knees.

When you lightly tap right above the kneecap on a fully relaxed and dangling leg; you must connect with the nerve that causes an instantaneous reflex. It feels strangely awesome...like a mini orgasm for the knee! Tapioca.
