Or, more politely, “The Former Guy” (as Biden has apparently referred to him a time or two).
You could use the numbers of his initials, 4:20.
After all, in the ESV Leviticus 4:20 begins “Thus shall he do with the bull.”
At least TFG has some origin outside of this forum.
When dipshits make up their own acronym and then use it offhandedly, expecting everyone to know what the fuck they’re talking about, that’s being an asshole. It’s like that moron in junior high who desperately tries to make some senseless and annoying slang they invented into a fad, and just looks pathetic.
Sheesh, I’ve been wanting to Pit these losers for a while. Thank you to the OP for the opportunity.

So, setting aside the kerfuffle over the o.p.’s overuse of a stupid and non-obvious acronym in an unclear context, the question of manslaughter begs actual culpability. Since both the incitement and the act occurred within the domain of Washington D.C. it falls under federal law, specifically 18 U.S. Code § 1112:
a) Manslaughter is the unlawful killing of a human being without malice. It is of two kinds:
Voluntary—Upon a sudden quarrel or heat of passion.Involuntary—In the commission of an unlawful act not amounting to a felony, or in the commission in an unlawful manner, or without due caution and circumspection, of a lawful act which might produce death.
(b) Within the special maritime and territorial jurisdiction of the United States,
Whoever is guilty of voluntary manslaughter, shall be fined under this title or imprisoned not more than 15 years, or both;Whoever is guilty of involuntary manslaughter, shall be fined under this title or imprisoned not more than 8 years, or both.
Obviously Trump’s tweets and words do not qualify as voluntary manslaughter. Could he have legitimately anticipated this death as a result of his incitement of a riot? Potentially, yes, especially since WDC and Capitol Police had been on alert for violent activity. However, nothing in his tweets and speech to supporters do not explicitly call for violent insurrection. Even his words, “We fight like hell. And if you don’t fight like hell, you’re not going to have a country anymore,” can readily be interpreted as allegorical political speech in the manner of politicians across the political spectrum who are not literally calling for violence. Joe Biden, Elizabeth Warren, and numerous other Democrats refer to “fighting” in reference to political conflict on a regular basis, and making the argument that the semantics of Trump’s call to battle was different than these isn’t going to pass a legal test.
Now, did Trump intend to influence the outcome of the election and force Mike Pence to refuse to certify votes? Of this there is no question because their is ample evidence of explicit attempts to affect vote counts and certifications in numerous states. Did he care if his words started a violent insurrection? No, Trump doesn’t care beyond his next meal, and if someone else’s violent act gets him what he wants, who is he to stop them. Could he have anticipated that Ashli Babbitt would crawl through a broken window and despite repeated warnings continue onward until she was shot by a Capitol Police officer? That is such a difficult case to make that no prosecutor is going to take that up. It’s a weak case made even weaker by the fact that it would be seen as a politically motivated prosecution, and even though Trump should be held to account for numerous crimes he committed during his presidency the chief executive is seen has having broad protections against prosecution lest they interfere with democratic norms, notwithstanding that Trump gives fuck all for any norms, political, financial, or regarding intimate familial relations.

… Eh, fuck it. I don’t wanna play.
Nm - misread the OP
I was being sarcastic, I used a smiley in lieu of /s 
I use TFG because I don’t want to befoul my mouth with his real name.
Name him and shame him. We do him more harm when we say things like “Donald Trump was the worst President ever” and “Donald Trump took bribes from foreign governments” and “Donald Trump was impeached twice” and “Donald Trump tried to overthrow the American government” and “Donald Trump has admitted to rape” and “Donald Trump paid off porn stars so they wouldn’t talk about how small his penis is” rather than saying all these things about somebody named Dumpster Fire or Cheeto or TFG.
There’s a simple solution if one has to use a cutesy abbreviation like TFG or PAB that may cause confusion: just make it a link to something that describes what it stands for. Say, for example, the OP could link to one of their several other posts in similar threads where they did the same thing and then had to somewhat rudely and condescendingly explain themselves.
In any case, never mind being guilty of manslaughter, in what sane universe is Biden currently polling behind trump in a general election rematch??!?? 
Have you noticed that people just refer to Hitler as “Hitler”? It’s because no name or acronym you could think of would be worse than calling someone Hitler.
Anyway… Donald Trump.
@Stranger_On_A_Train kudos and thanks and plaudits for seeking to answer the actual question.
The TL:DR of it is that the answer to the OP question is “that’s not how this law works”. Not every death happening any number of steps down a chain of consequences involving your words or actions makes you criminally liable for it.
(And OP, why in the Pit?? Just because it’s about someone hated?)
I thought it might get heated.
Let’s go to the quarry and throw stuff down there!

That really puts the pussy on the chainwax. P***y on the Chainwax - Key & Peele - YouTube
In one where “Anyone (R)” gets more followers than “Anyone (D)” because of relentless propaganda and the eletoral advantages of gerrymanderng and the EC. I think there’s not much more to it.
There have been times in the past when people here have said things like “I would vote for a chimp before I’d vote for an R for president”. The other side thinks the same thing. And this time they’re really being asked to vote for their chimp. Even if half of them don’t recognize he’s a chimp. We should be careful what we ask for rhetorically.
