What is what does it mean when a girl wants to smoke with you?

It could mean a number of things, and it ultimately depends on the context and the individual involved. Here are some possible interpretations:

1. She wants to hang out with you: If a girl asks you to smoke with her, it could simply mean that she wants to spend time with you and smoking is something that she enjoys doing. It may not necessarily be a romantic or sexual invitation; she might just want to chill out and have a conversation.

2. She's interested in you: Alternatively, it could be a sign that she's interested in you romantically or sexually. Offering to share a joint or a cigarette is a way of creating a shared experience and physical proximity, which can be a precursor to more intimate interactions.

3. She's looking for a smoking buddy: If you're both regular smokers, then her invitation might just be an expression of her desire to have someone to smoke with on a regular basis. This could be purely platonic, or it could lead to a closer bond if you find that you click with each other.

4. She's testing your boundaries: Depending on the context, her invitation might be a way of testing your willingness to engage in risky or taboo behavior. If you're not a smoker yourself, then this could be a way of seeing if you're willing to bend your own rules for her sake.

Overall, it's important to remember that every situation is unique, and you'll need to use your own judgment to interpret what a girl's invitation to smoke means in your specific case. If in doubt, don't hesitate to ask her directly what she's looking for.
