The species threshold above which a veterinarian will likely interrupt imminent sex to answer an emergency call. The first known example was documented in 1977 at Cold Spring Harbor Laboratory when the attending veterinarian answered a call about a flying squirrel just as things were "getting going."
Species above the flying squirrel line could include macaques, bald eagles, canines, ducks, voles, baby robins, and, of course, flying squirrels. Species likely below the flying squirrel line include danio rerio, xenopus laevis, and drosophila melanogaster.

A semi-beard or goatee - usually the result of a poor decision to display a lack of significent testosterone - compounded by insufficiant facial follicles. The resulting jeers have been the cause of much teenage angst and may have actually stirred the creation of the entire EMO generation. Also known as a face tail.

When you are so excited to have sex, that you cum, and shit at the same time. Typically happens the instant the penis touches the vagina skin.
