Meat Cake?
I'll match your Meat Cake with a:
Litterbox Cake
Which, if memory serves, is made of white cake and spice cake mix, crumbled vanilla wafers - some of which are colored with green food coloring, pudding, and microwaved tootsie rolls.
No, I've never made it, but it's a big deal in my profession. Some day I'll get up the motivation to make one for a covered dish supper.
Some add a few coconut flakes to the tootsie rolls to simulate tapeworm segments.
