Form drag, skin friction and interference drag on bluff bodies are not coined as being elements of parasitic drag, but directly as elements of drag. en.wikipedia.org

Small wrinkles are present in the skin that may have prevented separation of the laminar flow in the boundary layer and thereby reduced skin friction. en.wikipedia.org

This reduces lower-pressure effect in the slipstream, but also increases skin friction (in engineering designs, these effects must be balanced). en.wikipedia.org
