A batizado (literally "baptism" in Portuguese, and borrowed from the religious tradition) is normally an annual event for a capoeira group in a region or country.
Mestre Bimba, a founder of modern capoeira, recognized the central importance of relationships in people's lives, and he worked hard to nurture these connections, with the aim to help people develop into happy, whole individuals.
In capoeira contemporânea, batizados have developed in different directions with their own traditions, and while this is just as valid, it is so far from Bimba's creation that the only connection is in the name and not in its rituals.
In many schools, students are baptized by the floor, that is, they play against higher level capoeiristas and are subsequently taken down by a rasteira.
This ritual of giving a rasteira to the beginner is of modern creation, and is not a part of the original batizado ceremony that was created by Bimba.
