look up any word, like cunt:
A person who gets on Jayne's nerves.

Word created while Jayne and Spaz were doing something and Jayne morphed the two words "midget" and "idiot" together.
"Someone and Eiko and Loki and Silent and such are midgetdiots."

"That midgetdiot tried to wear alexander! So then, I stole him back and stapled her to the wall and used Chinese WATER torture."
