Most bris ceremonies include a number of guests present, beyond immediate family. Depending on how many guests, and depending on certain relationships beyond family and even with some rabbis, the ceremony could look very different from family to family in light of whom the parents of the baby might choose to have participate in the ceremony.
In Hebrew, the word כבוד (kavod) is often translated as "honor," thus the word for the honors given at a bris ceremony is Kibbudim. Those who are given these roles are the "honorees" in a sense, and every person in this category is described as "receiving a kibbud."
