I'm not sure if my readers have noticed, but Donald Trump has a rather unique follow-through on his handshakes as shown here:
One could term this move the "Trump Tug".
Here's another example of an interesting Trump handshaking style with Japan's Prime Minister Abe Shinzo:
It's interesting to note that Abe Shinzo's hand position is definitely giving the appearance of a limp wrist and that he does get a small "Trump Tug" even while seated. As well, the pats on the top of his hand by Donald Trump certainly make him appear to be dominated.
Not all world leaders have fallen prey to the "Trump Tug". As shown here, Canada's Prime Minister (and Nice Hair Guy) preempted the tug with his own move, a left hand on Trump's right shoulder as shown at the beginning of this video:
Of course, Trump's rather unusual handshaking style has been analyzed with some "experts" saying that it is a show of power or dominance over the person he is shaking hands with.
Now, thanks to the Relson Gracie Jiu-Jitsu Academy in Columbus, Ohio, we now have a defence for the "Trump Tug" as shown here:
Please note that the instructor does not advise that you use this move on the President of the United States since it is highly likely that the Secret Service may have something negative to say about it. I'd say that's quite likely the case.
