An insanely ugly person, usually hairy and/or disfigured in the face- male or female.

From the fact that someone half human and half mole would be ridiculously ugly.

Usually pronounced with the "o", with a slight sneer
ie: M -oooo-lechild.
Guy #1: Look, That girl is hot!
Guy #2: What?! Are you deranged?! She's a spiggin' molechild!

Person #1: "How was the party?"
Person #2: "Meh, There was a bunch of molechildren"
