I grew up in Philadelphia and I remember part of another “skin” game, similar to what you describe. You used someone’s forearm and you planted a garden (or something like that). As you said “first, you rake” you scratched the person’s arm, then you flicked as you “planted”, you spat, to “water”, slapped to “pat” down the ground. Eventually, red marks, (and a good planting left welts!) would result in the “harvest”. I can’t remember this exactly, because it wasn’t very nice, but it was clever!
