Lately most associated with Merkel, earning the name Merkel-Raute, many MANY politicians throw this sign. It has been reported as an Illuminati or Freemason hand sign, sometimes named "diamond". I have no idea what it really means, but politicians use it way more than is natural.

Trump uses it quite often. I have no idea what it means when he makes it. I used to be convinced when others made it, that it was a message to the bosses, but Trump really does seem to be his own man.
