Okay I got curious what/who thinks they can buy countries and looked it up. That answer makes sense. Why the PRC-like euphemism for Donald Trump though?
Oh, I got some sort of stock ticker when I typed it into a search engine. Though it was his company rather than his actual name. I also haven't ever heard someone use a third word in "Donald Trump", so in that sense it seemed to introduce obscurity (not that I'd recognise DT if nobody ever uses that) similar to using the "it's just the initials" TLA for China
Back when US presidents had long names we had JFK and LBJ. For whatever reason, the names have gotten shorter, and nobody's worried about fitting the name in an actually printed newspaper headline.
DJT is the symbol for the media company that owns his social platform. It's not the first time he's used his initials. He also used them for his bankrupt casino business.
DJT is not an uncommon reference though. Donald J Trump is common as well.
