Brain Fart - Bitch!

"Bitch" is apparently an okay word to use with my girlfriend, who in fact most of the time takes it in the affectionate way that most of the time I mean it.

But it's been suggested to me by someone that it might not be an appropriate word to use with other female acquaintances and colleagues.

Likewise "ho". I sometimes wonder if this whole "english language" thing isn't more trouble than it's worth.
