What is when you call a guy out on his bs?

When you call a guy out on his bs, you are challenging his behavior or statements that you feel are dishonest, insincere, or misleading. This can be done in a variety of ways, such as directly confronting him, pointing out his inconsistencies or contradictions, or asking for clarification. It is important to approach this with assertiveness and confidence, but also with a willingness to listen and understand his perspective. In some cases, calling out someone's bs can lead to a deeper understanding and resolution, while in other cases it may lead to a breakdown in communication or a further escalation of conflict. It is important to consider the situation and context before deciding to call someone out, and to do so in a respectful and constructive way.
