(1) As females grow older they increase in size. Their growth continues until the male of the species will no longer mate with her. At this point her transformation into a fat bitch is complete. After this the creature will spend the remaining days siting on the couch watching T.V. and spending the males money.

(2) see: rosie o'donnell ; a large hippopotomas like creature. Most noted for being "A" sexual, because of their ability to have both a penis and a vagina. Noted for spouting ultra liberal ideas that make no sense, along with insane conspiracy theorys.
That fat bitch sits on the couch all day. She let herself go. When i first wlked in i thought rosie odonell was on you couch. Lets leave her outside of an all you can eat buffet with the couch. If you are lucky she won't find her way home after she wakes up. Then you can find a new girl and go buy a new couch
