I'm broke as a joke but Jimmy loves me. I think I'll just have some gainalsex with him to pay my bills.

Gainersexual 

A sexuality that revolves more around eating food, gaining weight and fat worship as opposed to traditional sexual activities.

"Hey would you want to hook up? What do you like to do for fun in the bedroom?"
"I'm a gainersexual. So bring a cheesecake, some burgers and a stick of butter, and then rub my belly while I inhale it all."
