from The Century Dictionary and Cyclopedia
- n. Bride-cake. See wedding-cake.
Sorry, no etymologies found.
It's one thing to omit sending a man a piece of your bridescake, and quite another to knock off his hat in the street.
You know that nice smooth white sugar on the top of bridescake?
This is a custom still practised, but what is now the bridescake is not a cake broken over the bride's head, but a larger and more elaborately-prepared article, which is cut up and distributed immediately after the marriage ceremony.
