A slopbody is a girl who could look good but because she has not taken care of her body it kinda looks sloppy.
A slopbody are one of the two listed: Girls who were skinny then gained weight very quickly or girls who have a nice body but have islands of fat in certain areas.
After myself, Rude Dog, Crusty Joe, Perry, Big Roy and Dave had plugged Gina's gaping gash, she was left with nothing else but a Slopbox and a smile!!!
