That's actually not bad. I've been saying for a long time that there should be a demeaning nickname for Trump, as he uses them for others. Some commonly used taunts drive me crazy because they're essentially benign. I have a friend who keeps referring to him as The Orange Clown, and I hate these, because they mostly simply mock him as a fool, not the menace he actually is.
While I don't like taunting someone about their physicality ... I mean, I don't like it when people taunt him for being overweight, although a nickname like Fatso would certainly effective irritate him. But, while I don't like taunting someone for something like, in this case, his complexion, the term Agent Orange has a wonderful implication of long-term lethal danger, which I like.
