I suppose it can be taken a few ways: 1.) I'm suggesting McCarthy is as big as this vehicle. 'cause fat. 2.) I'm suggesting McCarthy is being wheeled around in a hearse -- a vehicle used for dead bodies. 'cause she's killing herself. with fat. edit: Further context: Melissa McCarthy is a giant fat woman who is a lead in the new Ghostbusters movie. She's mostly known for making stupid fat jokes at her own expense in every. single. movie she's in.
