Mysterious!notation?

[dvandom]

Okay, I keep seeing the "modifier!thing" construction in LJ posts. Since it's not part of any formal logical language I remember from Logic class in college, I'm guessing it's from a coding language. I asked razorsmile about it, but he didn't know either, just picked it up as a meme.

Can someone satisfy my curiosity on this?

In programming != means not, such as Megatron != Autobot.

In fandom it's kind of an adjective-prefix, I usually see it in places like crazy!Gaeta or crazy!Robin.

Yeah, that comes from the ~ notation used in logic, but things like crazy!Gaeta clearly doesn't mean "crazy not-Gaeta". Hence asking. :)

It's never made much sense to me, but I tended to accept it better after spending a couple of months reading Flea++ (http://halo.wikia.com/wiki/Seeker)
