yellow-haired pygmy

A young woman who continually attempts and fails to "steal" your significant other, though said other has no interest in anyone other than you. Often mistaken for a slut, this person lacks in social skills and finesse, and is a general tease to the male population. Not considered dangerous, but can be excessively irritating.

I would love to tear that yellow-haired pygmy's face off, but she's not worth the effort.
