In addition to hanging around in the Stack Exchange Chat, I also use a completely different private chat client to hang out with a very different crowd. They, too, are gamers, we enjoy lots of things together. I always refer to them, though, as "the other side of the internet" (and over there I use that same term to refer to here). Because while in both cases I'm talking with people, they're very different sorts of people with very different sorts of upbringings.
It's a very different culture there. There, that place is a group of people of all ages, races, and every other distinguishing factor, who practically have their own nuances of language that they use amongst each other, but this is solely because they are amongst themselves. Because one of the most important things is that language is not something you bring to the table yourself, but it's something you share with your audience. Bringing a foreign dialect into a new region and expecting everyone to understand where you're coming from is, well, hopeless and likely to get you into harm's way. When each and any one of us steps out of that circle, we speak completely differently. And that's not faking or anything, it's simply embracing the very real aspect of how language works in communities.
Perhaps in your circles and other places, that terminology you used may be seen as okay. I can certainly see it, in some ways, as a linking factor between people of common backgrounds. But we're not automatically those places. Stack Exchange Chat is particularly different from most chat clients - while we have separate rooms for separate communities it is still one big, global, professional space. What works for a handful of people might not work for some other people - which is why we have a flag system in the first place.
Don't dwell on it. Don't assume that people are out to get you and are willing to twist things just to do away with you. If you understand already that this kind of communication works within certain circles, then you should understand that the corollary is that it does not work in other circles.
