I'm going to call my brown girlfriend burnt
Is this something that you think your girlfriend will laugh at?
I tell you one thing it's such a shame that black people cant take a joke.
It is normal to have inside jokes with your significant other but you should be careful not to be racially insensitive and hurt them when joking around with them. Even if your girlfriend was okay with it, others will think that you are a racist.
It's not racist, I love her and I'm not offending anyone.
Whether you were trying to offend her or not, your joke could come across as racially insensitive. Try to explain to your girlfriend that you were not trying to make her upset with the comment and hopefully she will believe you.
