Psychowhatsits make me confuse. It seems to be the science of taking simple stuff humans do and explaining the reasoning behind it in the most complicated manner possible, and also giving said simple interaction a really, really weird name.
That's generally because the shit people call simple interactions usually
aren't when you actually start thinking about them and trying to break down what the zog is happening.
It's so incredibly removed from reality it's hilarious.
... from what I understand, the behavior described is actually a thing, somewhat clinical/stilted wording of the question itself aside. It's not so much removed from reality as looking at it funny compared to the socially normal viewpoint.
It's like, yeah, you're dealing with something you're not familiar with the terminology or methodology related to it, but these people usually aren't pulling things entirely from their ass. And hey, it being like some kind of nature documentary is kinda' the point, a lot of times. Because a fair amount of psych and whatnot more or less is, just with humans instead of other animals.
