Final answer:
Teasing about sensitive topics or sharing secrets to harm social status is known as relational aggression, a form of psychological harm focused on damaging relationships or social standing.
Step-by-step explanation:
Telling another's secrets or teasing about sensitive topics is called relational aggression. This type of aggression is used to harm someone's social relationships or status within a group. It is different from overt aggression, which involves physical threats or harm, and contrasts with reversed or volatile aggression, which are not standard psychological terms in this context. Relational aggression can include behaviors like spreading rumors, ostracizing individuals from a group, or sharing someone's secrets without their consent.
