You should come meet my bitch. She's the one on the phone.
This statement is not ok by me. Did you mean to say that your girl is a bitch?
Yes, it is totally fine.
Calling women, like your gf, bitches degrades them and that is not correct. Find a respectful way of referring to the woman that you love.
What does it matter? Are you ok? This was only a joke. Don't take it so serious.
You have to be more respectful towards women in the future. It's really bad to call them names and treat them that way.
