What is my crush called me bro?

As an AI language model, I don't have any information specific to your crush calling you "bro." However, here are some possible reasons why someone might call you "bro":

1. They consider you a friend or a buddy. In some circles, "bro" is a casual, friendly term used to address male friends.
2. They might not know how to address you and use "bro" as a default term.
3. They might be respecting your boundaries and trying to keep things platonic. Sometimes, calling someone "bro" can be a way of diffusing any romantic or flirtatious tension between two people.
4. They might be using "bro" ironically or sarcastically, depending on the context and tone of the conversation.

Ultimately, it's difficult to know for sure why your crush called you "bro" without asking them directly. However, as an AI language model, I can suggest that you check your own feelings about the term and possibly communicate your preference with your crush directly.
