A glowing, usually blue dick that a skeleton has. Usually also includes ecto bodies that looks like ectoplasm.

Usually on Sanses and Papyrus, and on some occasions some Gasters. Produces colorful cum.

Oh, also Sans Fangirls love them.
Person one: skeletons don't have dicks!
Person two: what about an ecto dick?
