Instead of talking to him like a regular couple? You know, communication?

I think once he uses your grandpa to make a blow job joke on Facebook, the time for talking might be over.

Nah, I'm pretty sure its enough info about the guy.

Yeah, if he wants to be a smartass, then he should first consider being smart, otherwise he's just an ass!

But it wasn't even funny. At all.

I know. He was being dumb but oh well we can ignore the rest of my post too I guess.

Not to mention the disrespect he showed to OP on a public platform no less.

I don't get this define "ok" in my family it's only crossing the line if the joke puts someone's life on the line to some maybe there's a clear line..in others this would be bloody hilarious (my grandpa and dad would laugh over something like that..my sister would be a bit upset but more because she's weirdly closeted in terms of sexuality for our family)

That's exactly why it's not okay, 69. Just because something is funny or acceptable in your circle of friends or family does not mean you should assume it's okay with everybody.

but how would she not know her bfs sense of humour enough to already have such a talk? she should know his sense of humor

How does this have anything to do with her? Maybe she knows his sense of humor, maybe she enjoys it. That doesn't mean she should desire or expect it when posting on a public place like Facebook. He should just grow up and realize that there's a time and place for everything, and generally public posts (especially after elderly family has already seen/commented on it) are not the place for such humor, regardless of whether or not she enjoys it.

Yeah, I think he just blew in from Stupid Town lol
