look up any word, like blumpkin:
A Ruby is a large breasted creature with long brown hair, who seeks out men with small penises. when she gets horny she lurks around awaiting her next victim. if you meet one be sure you run away but beware she is very fast
also.. she is bi-sexual so girls be prepared for a loooonnngg night if you come across this wild beast...
