Il Douche, I’m not one to use gender based insults, as a rule, but it sums up how I feel about the man, and his political doctrine.
America-hating Fuckstick.

Just saw the pic of Trump grinning prettily for Vlad, so…
Donny Dirty Knees
Doesn’t matter what you call him. He is still your president if you are citizen of the United States.
He doesn’t think so.
The Grump
Yeah, I know there’s a muppet named that, but it fits.
The funniest one is “Ill Douche”, but I rarely if ever use it. I use a mix of “The President”, “45”, and “CFSG” depending on how obvious the reference is by context.
That reminds me:
Illegitimate Usurper
“so called” president
White trash piece of shit
I like this one a lot. It has a genuine quality because it was penned by Tammy Duckworth, who knows more about toughness than Trump could ever comprehend. Me, personally, I just call him by his actual name. I do, however add an incredulous “motherfucking” as a middle name. Because I am still incredulous at the gullibility of so many Americans with their support for him. The dude has always been known as a con man. That’s the nice way of saying it. He is the poster child for con men, the example of an over the top not even believable liar. And the Republicans still went all in, and continue to make excuses for Donald Motherfucking Trump.
I’ve been using Douche L’Orange. And Orange Turd.
I’m still pretty solid on Donnie Two Scoops because for me it highlights his spoiled toddler nature and at the same time it sounds like a mobster thug nickname.
The Stable Genius is still a favorite because if you are you don’t need to tell people.
Dotard is another good one.
Cheeto In Chief.
iDJiT; DJT for short.
Trump the Chump works for me!
And you will continue to be an ass in Trump related threads. Not gonna stop us.
“IQ 45” is what my wife generally goes with.
ETA: Don’t see “Cheetolini” yet. 
When he tries to BE President of the entire country, rather than of just the 42% who are his fan club, you might have a point.
I’ve kept a list:
Cheetolini
Dolt 45
Mango Mussolini
The Abomination of Desolation
The Shitgibbon
The Short-Fingered vulgarian
Cheeto Jesus
Our Nutcase-in-Chief
President Tangletongue
I’ve never even opened the big three (I assume) Trump threads. I wouldn’t want to make you uncomfortable in your safe spaces.
Locally: Gritty’s oranger drooling idiot cousin.
