Donald Drumpf. Doesn't have quite the same ring of wealth and power as Donald Trump, does it? I mean, President Drumpf? Not bloody likely. Drumpf Towers? Nah. Drumpf Casino? I wouldn't spend a dime there. So the Donald can thank his lucky stars that his grandfather, Frederick Drumpf, started calling himself Frederick Trump. It's not known, according to the website Bustle, "... if he ever changed his name officially. Some have speculated that he didn’t want to be known as “Drumpf” because of prevailing prejudice against Germans (which would heighten, of course, during World War I)."
Still, the name Drumpf has spawned all kinds of spoofs and memes on the Internet, including more than one hashtag on Twitter. #makedonalddrumpfagain trended for days, and there's a website where you can get a "drumpfinator" extension for Chrome that changes the word Trump to the word Drumpf on every page you view.
