What sort of "friends" call each other offensive names like the b-word?

The exact opposite.
That name calling is reserved for close friends.

Ive had some friends for most of my life, some as long as 30 plus years. We do sometimes call each other names and tease each other relentlessly. We just don't take these things so seriously. It works for us, the more we tease you, the more we love you. Btw I'm a "water" sign and I [b]don't[/b] take it seriously at all. If others know you are that sensitive about words, they might tease you or insult you to get a rise out of you. It's not worth getting stressed about it in my opinion. But to each their own.

These type are the most dangerous people, it's well known that john wayne gacy called everyone a bitch

Overly nice friends who don't call you offensive names to your face are the ones who are doing it behind your back. Also here we can barely get through a sentence without saying cunt.

It's only problematic if someone isn't okay with it.
If you don't like it, don't refer to your friends as bitches and they won't call you one.

My friends and I call each other this because we know we are bitches but also because we trust each other and love each other. It is called close connection. If you don't understand it, that is your issue not anyone elses.

I agree with you on this point. That makes no sense to me, either. I try to be kind to my friends, not call them ugly names.
