spergatroid
A mild insult applied to someone who exhibits nerdy or socially awkward behavior resembling one of the symptoms of Asberger Syndrome; for example, the repetitive door-knocking by the character Sheldon on The Big Bang Theory. Adapted from the "Heavens to Murgatroyd" exclamation by the cartoon character Snagglepuss on The Yogi Bear Show.
He's such a spergatroid. He can quote any scene from Star Trek but can't flirt with a girl.
