Beat rime to call your new girlfriend

I think you meant "beat the game"!

If you're referring to the popular video game "Beat Saber", you can definitely call your new girlfriend after completing the game or achieving a high score. However, if you're looking for a more creative way to ask her out, you could try something like:

"Hey [her name], I just beat the game and I'm feeling like a total boss! Want to be my next challenge?"

Or, if you're feeling more playful:

"I just sliced and diced my way through Beat Saber and I'm ready to take on a new challenge... like asking you out on a date!"

Remember to be respectful, considerate, and genuine in your approach, and I'm sure she'll appreciate the effort you put into asking her out!
