That is the term I was searching for, but I think I have just had to coin it after the moment passed. I can only find "differently socialized" (they're American, so that's fine,) which is talking about socialisation of dogs vs wolves.
I have just had a strange exchange where I tried to explain that I am differently socialed. Although I dislike shit along the lines of 'differently abled', I like my term because I enjoy applying an odd type of humour to myself.
I have just been shocked in a good way, because the founder of a social networking type site has asked how I like it. And they explained something about the way it works that really was very informative. And, and - were behind an old site that I still miss.
I suspect it was like a standard message thing, but I still rate it highly to even care enough to ask in a formulaic way.
