I use "The Trumpster". Has appeal to me because it feels like the type of nickname that comes out of the juvenile eighties and has a "frat boy" vibe ,like "the Mooch".
Further, it rhymes nicely with "dumpster" (something that fills with garbage, frequently stinks, and needs to be hauled off).
The Russia summit might rightly then be described as a "Trumpster Fire".
Edit to add, I have never been particularly fond of name-calling. Always looked at it as bad behavior that no one I could respect would engage in. Then 2016.
