What is what does it mean when a guy calls you bad asf?

When a guy calls you "bad asf" (with "asf" being an abbreviation for "as fuck"), it typically means he's expressing admiration or attraction toward you. In this context, "bad" is used as slang to describe someone who is highly attractive or appealing. It's often used to compliment someone's physical appearance, confidence, or overall demeanor. While it's generally intended as a compliment, it's important to consider the context and the tone in which it's said, as it might not be appropriate in all situations or be well-received by everyone. Communication and personal boundaries should always be respected.
