Fake-bitching. When someone bitches for the sake of agreeing with someone, rather than because they actually feel the need or severely dislike the person.
sha'naynay: omg that girl is such a skank! she stole my boyfriend!
Bitching with feeling
When you talk about someone you know but try to understand what they're going through.
"Hey, how's it going? I saw my friend Ella the other day and she was having an argument with Jamie!"
"Again?"
"Yeah, but I understand that she must have some deep issues"
"That's so true"
"Okay well, see you later good fitching sesh babe!"
"See you later!"
