An explosive enjoyable sensation on an orgasmic level felt only in the palm of the hand after a mind-bending arm and hand tickle. The technique for giving someone handcum is to run one's fingernails down the arm slowly and methodically, intermittently touching the palm but leaving most of the activity to the arm until the person is in a fit of passion and cannot stand it anymore...then you scratch the palm. Fast.
You just made my handcum. Now do the other one.
