So I pissed off my Girlfriend...

weeb dont paint all women with the same brush, we can take a joke :P his gf clearly could

After a few hours. A women's sense of humor is the most selective thing in the world. She'll be laughing with you one second and the next she is pissed and ignores you.

The first thing I would do is ask random people on the internet after 3 hours. They don´t know you nor your girlfriend and don´t know what she is like. Maybe just wait a few hours more explain her the situation and talk about it on the next day when she calmed down?

I think you need to retake middle school biology class if you think the only difference between a man and women is the uterus.

I usually hate the hipster kids that complain about being born in the wrong generation, but weeb... you really ARE born in the wrong generation. I'm sorry, man.
