The external weight being him?
I was thinking the Burger King, Wendys, McDonalds, Taco Bell, pretty much anything she can get her short stubby T-Rex arms to, but sure him too. I want to describe him as like a remora, but I think he's the primary bread winner so that's not an apt description. How do you describe two turds who circle each other, feed off each other and contribute nothing to society?
