Instead of merely rubbing the inside of your hand down your asscrack and exposing it to dingleberries and ass-sweat and then proceeding to shake someone's hand or touch someone's food, you actually stick you WHOLE FIST into your rectum and proceed to shake someone's hand or touch someone's food. In reality, this act is much more self-detrimental than stinkpalm, as you actually have to stick your fist in your own ass to perform it. Extremely disgusting.
