A Roce (or Ros as it's otherwise spelt) is a traditional Mangalorean Catholic ceremony whereby the bride and groom are annointed with a mixture of coconut milk and oil (the roce), and then blessed. This often takes place on the evening before the wedding.

It signifies the end of bachelorhood and spinsterhood for the bride and groom.

Roce is applied/poured on the bride/groom as a sign of washing away the sins and purifying the soul for marriage.

The mother of the bride/groom starts the ceremony by drawing a cross on their forehead as well as pouring a few drops of it in each of their ears. This ritual is then followed by family, siblings, friends, and the guests taking turns to anoint the bride/groom with the Roce and oil.
