A bitch that is really fat and disgusting. She can usually be seen beached on the couch and flopping around on a bed. Her daily activities include eating, sleeping, and pooping.
Husband: Hey can you clean the house today? I would but I work 60 hours a week.
Wife: (beached on the couch) I don't feel like it.
Husband: Don't be a whalebitch!
I created a theory called "Whaletivity" basically for any group of decently looking girls or just girls walking around in general there is always a fat/ugly one with them or near them.
Go to the mall or look in your school's hallways and prove me wrong.
