Hopefully I can write this out without getting too ranty as I'm feeling pretty frustrated right now, apologies in advance if this goes off the rails!

I'll set up who's who in this situation I have my two best friends who are 10 years older than me I'll be calling them B and W.

B was dating a guy called P, they were together for only three weeks and he broke it off saying he didn't feel much of a connection and didn't want to waste her time. I think this is completely fair as I recently ended things with a guy because I felt no connection with. Both B and W have been very supportive of my decision but have been bad mouthing P for his. The hypocrisy is frustrating to me and I don't really know how to point that out without sounding like a bitch. 

Also I completely understand that B is hurt, she was trying to come up with a "code" name for P. She ended up calling him Small Penis P___. W laughed at it and said it was good. I feel hugely uncomfortable laughing about something a guy has zero control over. So when she came up with the mean nickname I did speak up and say hey there's nothing wrong with small penises anyway that's not really fair to him. So B's compromise was to refer to him as SPP now. I still don't like the connotations and I'm wondering how I can point out how devastated she'd be if she found out an ex called her Small Boob B. Or SBB. (She has terrible body image and is extremely self conscious). 

Anyway this morning she sent a meme to W and myself of that guy in front of the moon trying to pinch it with his fingers but being completely off and the title is "Men trying to find the clitoris". She captioned it "sex with SPP". W's reply was "LOLOL SPP". I felt terrible! Another thing about P is he hadn't been in a relationship nor had sex in three years (we all know this, he's a friend of friend). So of course P was going to be rusty and nervous sleeping with her.  I ended up replying "oh too bad female anatomy isn't properly taught". Also true, the poor guys haven't got a clue because they don't have clits themselves and sex Ed ever teaches it.  I'm so angry because these are 40 year old woman and I'm wondering why the fuck she just didn't tell him or guide him to get to her clit if that was an issue. 

Basically I'm looking for advice on what to say when more SPP jokes roll in or when they get on the man bashing train they've been riding lately. I completely understand they've been through divorces and broken engagements in the past so they're a bit more bitter than I am in the love department but I've had my fair share of devastating heartbreaks but I would never try to shame an ex to make myself feel better. I also have little sister vibes with them where I don't always feel like they take what I say seriously. 

Any advice or recommendations would be super appreciated!
