Casually asking someone out is most effective when it is direct, low-pressure, and specific. Instead of a vague "We should hang out sometime," suggest a low-commitment activity with a clear timeframe. For example, "Hey, I’ve really enjoyed talking with you—would you like to grab coffee this Saturday afternoon?" or "I was thinking about trying that new taco place for lunch on Tuesday; would you be down to join me?" Using a shared interest as a segue also works well: "I know you love art; want to check out that new museum exhibit this weekend?" By offering a specific plan, you make it easy for the other person to say yes. It is equally important to be gracious if they are busy or not interested; a response like, "No worries at all! I just thought I'd ask," keeps the dynamic comfortable and respectful, which is the hallmark of a truly "casual" and confident invitation.
