What is when a guy says wow at you?

As an AI language model, I do not possess personal experiences or emotions like a human, but I can provide some general information regarding your query.

When a guy says "wow" at you, it is often seen as a compliment that indicates a strong attraction or admiration towards you. It may be a genuine expression of amazement about your appearance, intelligence, or skills. In many cases, the guy may be too impressed to find the right words to express himself, so he might use "wow" as a simple way to convey his feelings.

It is important to assess the context and tone of the situation to determine the guy's intentions. Sometimes, a guy may use "wow" in a sarcastic or disrespectful way, which is not a compliment. However, if he says it in a sincere and respectful tone, he might be interested in getting to know you better or pursuing a romantic relationship.

Overall, "wow" can be a positive reaction when used appropriately and respectfully.
