This term comes from a key theology in the book-the Seven Gods, in which there are seven gods and seven days, so there are seven levels of hell. This word is often used to express anger, pain or surprise, but it is not limited to these emotions.
The belief in the seven gods is the most important religious belief in the seven kingdoms, and people often simply call it the "church". On the continent of Westeros, there are only two places where people do not widely believe in the Seven Gods. One of them believed in the northern boundary of old gods, and the other believed in the iron island that submerged the gods.
The belief in the seven gods is actually seven forms of worshipping the same god, and each form is in charge of a stage of life. In order to simplify the concept of form, bishops often refer to each form as a separate god.
These seven gods are:
Father stands for judgment, and people pray for justice to him. Father is often described as a man with a beard and scales.
The Virgin Mary represents maternal love and upbringing. People pray to the virgin Mary for more children or kindness. The Virgin Mary is often described as a woman with a loving and kind smile.
Soldiers represent strength in battle, and people pray for courage and victory to him. The soldier is wearing a long sword.
A young girl represents innocence and purity, and people often pray to her to protect her virginity.
Blacksmith represents craft and labor. When there is work to be done, people often pray for strength from blacksmith. The blacksmith is holding a hammer.
The old woman represents wisdom, and people often ask her for guidance. The old woman is holding a lantern.
One of the seven forms of strangers represents death and the unknown. Believers seldom ask strangers for help, but homeless vagrants often associate with strangers.
