Would it be possible to distance yourselves from the friend who keeps hanging out with the annoying new guy?

For example, stop inviting him over? etc?

And if the guy asks, just say: "hey, you always bring annoying guy, so we didn't invite you this time."

Be direct. Be honest. Tell him what bothers you, ask him why he wants to hang out with you, ask what started him hanging out with you, stop dropping hints, that is dick, be direct. Just talk to him like a HUMAN BEING. Being PC is total BS and is a huge problem with what is wrong in this world (badpeople hiding behind good behavior.) You don't have to be mean about it, of course.

Last post on this thread, you say this fella is 32, how old are you and your mates?, is there any chance this person suffers from a degree of autism?

Oh. I was betting on being the leader of the group of child molesters that talk at the theater.

Sometimes you gotta do the dirty job whether you like it or not. I would explain the situation kindly to him, he will of course not take it too well and if you start avoiding him and excluding him from the group he might eventually leave by himself. If you only know this guy online, living in different countries and never met, then you should be even more inclined to speak with him.

I've had a similar situation with a friend I used to go to high school with, he used to come to my house almost every morning, Imagine you still didn't wake up and he's already there. I told him it's annoying to do that, he took it bad (and so did I partially) he was a nice person, but he distanced himself. We still spoke after that but it wasn't the friendship it used to be.
