disembodied penis
A penis that appears to be magically floating in midair, detached from any body.
Usually this is so an artist can draw a penis without having to draw a male body in the way of the female character.
For it to be a true disembodied penis, it can't just be that the body is out of frame. It has to either fade to nothingness at the base or be otherwise clearly detached.
