A large girl with a rather fat stomach, so that when you are humping them the fat starts slapping together...
She's a real fatslapper...

One who sits around and does nothing useful for anyone when there is work to be done. Thus, this makes the person fatter, and they become proud of it.
"Get off your ass, you lazy fatslapper, and help me move this body into the trunk."
