Ate the hind leg off the lamb of God

exp.

Heard in Waterford and Galway

An irreverent saying used to describe extreme desire for food.

In use

I haven't aten anything since breakfast, I'm so hungry I'd ate the hind leg off the lamb of God.

Posh English

I have not partaken of so much as a morsel since breakfast, and I am now so ravenous I should devour the hindmost limb of the Holy Lamb itself. Heaven forgive me.
