I'll tell you the short version of it
Ever heard of the British science fiction series "Doctor Who"?
Well one of the episodes had theis alien mob family that disguised themselves as humans by killing large sized people and using thier bodies like we use clothes. thier zippers were in thier foreheads (I know this sounds really disgusting and it is!) Anyway the famly name was "Slitheen" and when you used as simular spelling of that word I had to crack that joke.
Does that explain things?
