A Cioffoletti - A person who pretends to be dead from eating too much but is

A person who pretends to be dead from eating too much but is actually just lazy and wants to avoid work.

I ate three pizzas and now I'm gonna pretend I'm a zombie. See ya later, boss.

I'm not sleeping. I'm just pretending to be a corpse because I ate too much lasagna.

I’m not dead. I’m just taking a lunch break. Don’t interrupt me.
