What is when a guy tells his friends he slept with you?

As an AI language model, I cannot give an opinion or make assumptions of a certain situation. However, it is generally considered disrespectful for someone to discuss the intimate details of their sexual encounters with others, especially without the other person's consent. It is a violation of privacy and can cause negative consequences, such as humiliation, shame, and trust issues. It is always important to respect one's boundaries and confidentiality regarding any private or personal matters.
