A very large and extremely hairy female. They are morbidly obese but look slightly muscular in the fore arms which are covered in matted black hair. Usually sporting mutton chops and a mustache. For your own safety NEVER I MEAN NEVER approach these creatures when they are feasting. You will be incorporated into the meal. When these beasties are horny and wishing to mate the can be found in the usual watering holes amongst the bar flies and swamp donkeys. Give serious thought before deciding to mate with one of them as one night stands do not apply and like a coyote you will end up chewing your leg off to get away. Best viewed at a distance.
Goneril is the eldest daughter in Shakespeare's King Lear.
Goneril treats her father well, until he becomes old, and gives her and her husband a plot of land and a lot of money. Then she starts treating him really crappily.
A girl, or guy, who is described as a Goneril, is someone who abuses and takes advantage of those who love him/her the most.
