(noun, usu. female) nymphomaniac of the submissive variety, extremely devoted and generally long-sufferingly obedient to male members.

Derived from but not to be confused with cocker spaniel. Heavy and/or sagging breasts are not part of the definition.

Would you look at Denise? The longing look in her eyes when she sees a bulge in anyone's pants. She's such a cock spaniel!

A domesticated member of the family canidae, not necessarily a cocker spaniel, which jumps up on the bed while two humans are engaging in heated intercourse. This usually occurs right as one is about to climax.

This unwelcome interruption completely ruins the moment. The offending dog, which may or may not be a cocker spaniel, is usually jolted off the bed by a quick kick, followed by an awkward resumption of intercourse.

Note: the dog must be a cocker spaniel.
