Also known as: 阴茎阴影
A Shadow cast by a Penis (or something shaped like a penis), usually on a character's face.
This tag applies even when the real Penis is not exposed. If the penis is visible, add the Penis tag.
If the object casting the penis-shaped shadow is actually something innocuous, add the Phallic Symbol tag as well.
Not to be confused with Invisible Penis, which is when the penis itself is drawn as a shadowy shape.
