Yes, it’s Ontario.
Do you mean the Canadian province, the city in California or another Ontario?
Oh, right. Ontario, Canada.
So, uh, no chance you are going to answer any other questions about this story?
There doesn’t seem to be anything new to report so far. He hasn’t had any trouble with them the last few days.
No, I mean the questions pertaining to the absurdity of this story and the fact that it almost certainly isn’t happening at all.
Also, the OP is ekedolphin, whose landlord is a fan of the America-hating fuckstick. Subtly points to the US (even if not California), more than Canada.
I know the story sounds absurd, but my friend tells me it’s happening. She’s an internet friend I met on my writing group; I’ve not met her in person.
I’ve been told lots of things by lots of people. A lot of them weren’t real.
A couple of specific questions:
What is stripping, as you use it? From context I don’t think you mean strip tease.
You say the dude is well off. How does he make a living?
How did he meet a woman who slept with lots of Hell’s Angels? What’s his connection to that scene?
Have the Angels directly threatened him? Has your friend witnessed this?
Why would the Angels go after some random person because some woman told them to? Why would they care about an individual selling drugs. Lots of people sell drugs in Ontario.
Three possibilities:
You aren’t getting the whole story. Your friend’s friend has a problem with the Angels, but it isn’t what you or your friend think it is. He really pissed them off in some way, like he screwed them on a deal.
This is meth induced paranoia.
Your “friend,” whom you’ve never met, is setting you up for a long con. Expect a request for money soon.

Almost thirty years ago, The New Yorker printed this about the Internet and how much you should trust what people are telling you.
That cartoon is a classic, and has been parodied many times. Didn’t realize this was where the phrase originated, assuming it did here.

Maybe she’s just practicing her fiction.
This case is certainly fake, but even if it were true, this is the wrong crowd to ask how to handle it. You need to find a message board with a higher ratio of convicted felons who have experience dealing with that.
An old friend of mine was a biker with experience in an international motorcycle club. From the experiences he shared with me, one doesn’t “get the Hell’s Angels off your back”. If there’s been an affront, members of the organization respond immediately and with great force.
True, but my experience with OMC members has been that they are pretty shrewd and actually easy to talk with when treated with respect. One time I needed to find some old Triumph parts and I was told that “Ace” had some in one of his old trailers. He took me to his home and spent quite a bit of time sorting through his junk piles to find exactly what I needed. Even offered me some iced tea or a beer while he was working. We chatted a bit about my 1962 Triumph and I walked away with several parts at a reasonable price.
A week later, he and his GF showed up at my house at 11:30 PM driving a beat-up Delta 88. He wanted me to get in the car and come with him. On the way, he explained that he had been riding his own 1963 Triumph and had been stopped for DUI. He was forced to leave the bike where it was. His GF came to pick him up and he needed me to ride the bike to my house to store it until he could trailer it. Why, you might ask? Because Triumphs of that era had right-side shifters and left-side brakes. He didn’t trust anyone to ride it who wasn’t experienced with the shift/brakes set-up. I got it to my house and, a few days later, four or five guys with a trailer showed up to get the bike.

Totally agree.

That is true when dealing with members. It’s a different matter if you have affronted the club as the OP claims that Z has done. They won’t be reasonable about that.

Has he considered baking them a lasagna?
Or invoking the Flos Carmeli prayer. I hear that always works.

When I was working in Japan at my first job in a Japanese company, and we were introduced to a new customer. My boss and I went there, and the guy seemed alright, but then his underling came in with a phone call. He stepped out of room to take it and switched immediately into a really rough yazuka type of speech. My boss and I decided we would pass on the business. They are OK, but can become quite unreasonable, even if you try to be respectful.
