The scientific theory in Ghostbusters is that the cohesive part of a spirit is an ectoplasmic residue, which is left behind in our realm if it comes into contact with a ghost. This has been discovered in a few paranormal investigations, but there is no scientific proof that the ectoplasm came from an incorporeal entity. Ghostbusters would not be a funny movie unless there was a common occurance of being attacked by a ghost... like that of Peter Venkman getting "slimed" from head to toe in green goo.

He wasn't a ghost. He was a giant Stay-Puff Marshmallow Man. He was made of marshmallow.
His name is Slimer. Although I don't think he had a name in the actual Ghostbusters movies. I think he was only given a name in the cartoon TV show that was on in the late 1980s to early 1990s.
