Donald Trump's handshakes have become something of an online phenomenon.

At every meeting between Trump and one of his fellow world leaders, a large proportion of the internet is less interested in the substance of their talks thank it is in the handshake between the two.

"The handshake is the ultimate focus of anxiety for a certain sort of self-conscious man, " the Telegraph's Rupert Myers wrote earlier this week.

"Trump has imbibed deeply from the well of bad self-help guidance to project success. The apogee of his performance is the handshake, the 'Trump Pump'; for all the catastrophes of his Presidency, we shouldn’t overlook how ridiculous the pump is, and how symbolic it is of his approach."
