giblets

giblets \JIB-lits\, noun:

The heart, liver, gizzard, and the like, of a fowl, often cooked separately.

-- Margaret Atwood, The Handmaid's Tale

Whatever you say to such people, they think you're talking about their problem, like the story of the cat, where the couple was arguing about a divorce but the cat thought they were disagreeing about the giblets for its lunch.
-- Umberto Eco, Foucault's Pendulum

Giblets most likely derives from the Old French gibelet, "a stew made from wild game."
