Piss posturing

[Donald Trump]

Piss [Posturing] = Personal Interest in Social Situations (PISS). Some people fake that they have a sincere personal interest towards one individual in front of others in a social situation. Imagine a CEO [holding court] at a work function dinner table asking questions of a new junior associate. In the case of Piss Posturing, BOTH the person showing the interest, and the person receiving the interest KNOW that the person showing the interest doesnt give a damn about the other person. Its purely a SHOW, a [posturing], to show others how [personable] and humble the person showing the interest is.
The person being shown attention feels as if he/she is being PISSED ON, and both he and the other person know it. Down deep, despite smiles on the faces, [the junior] associate is thinking You dont care about me, youre pissing all over me in front of these people and theres nothing I can do about it.
