Insult

• The use of the word X as an insult occurred through its association with the Greek/Roman goddess Artemis-Diana, the goddess of the hunt. 
• Artemis-Diana was often portrayed in the company of Y (X),and sometimes as __~X__ herself. 
• In order to suppress the sacred feminine and to impose Christian rule and ideology on non-Christians and pagans, the expression Y was used in Christian Europe to impugn those who were the spiritual followers of the goddess
