In the context of the early 1900s, "skin" is used as a verb meaning to move swiftly or slip away. It is related to phrases like "skin out," which means to leave quickly or hastily. This usage likely stems from the idea of "skinning" as a quick, slick action, akin to how one might swiftly peel or slip off the skin of an object. The origin can be traced back to the notion of moving in a smooth or gliding manner, possibly related to older idiomatic expressions involving quick actions.
