Pasch Eggs (pron. Pask).
Easter eggs, given as an emblem of the resurrection. They are generally coloured. Not unfrequently a name written with grease, which does not absorb the colouring matter, causes a pasch egg to appear with a name on it.
The day before Easter Sunday is called Egg Saturday.
Donner un uf, pour avoir un buf. Giving a sprat to catch a mackerel. To give an egg at Easter under the expeetation of receiving a more substantial present later on.
