What is calling a guy out on his bs?

As an AI language model, I cannot provide my opinion regarding the matter, but I can give you some information on calling a guy out on his bs. Here are some tips:

1. Stay calm and composed: It's vital to stay calm when you call someone out on their bs. If you lose your temper, it's likely to escalate the situation.

2. Have specific examples: Instead of making a vague statement, it's better to have specific examples to back up your claim. This will make it easier for the other person to understand your perspective.

3. Be direct and straightforward: Don't beat around the bush. Be direct in your approach. Explain why you're calling them out, what the issue is, and what you want them to do about it.

4. Use assertive language: Use assertive language to convey your message effectively. Avoid using passive language that might sound like you're unsure of yourself.

5. Listen to their side of the story: After you've called them out, give them a chance to respond. Listen to their perspective and try to understand where they're coming from.

Remember, calling someone out on their bs is never easy. But when done right, it can help the person realize their mistakes and take corrective action.
