a portmanteau comprised from Trump + narcissist + pisser + pissant + pissist + pissing + fetishist
def: see Donald Trump, the prototype ; a person (usually male) whose behavior demonstrates he is obviously mentally deranged, exhibiting the primary hallmark of extreme pathological narcissism; the diagnosis is certain if this sign is seen in combination with any two of the following diagnostic criteria:
(a) pissing fetish;
(b) grabbing women by the pussy (or, in the rare instance of being a female ... any public grab-a-snatch display;
(c) daily Twitter rages;
(d) weird orange tint to skin or hair;
(e) pathological lying;
(f) befuddlement and incoherence of public speech;
(g) unnatural (and very obviously so) small hands or penis;
(h) fascination with tyrants and megalomaniacs
Donald Trump is the prototypical Trumpissist; he exhibits both diagnostic signs (1) pathological narcissism + (2) pissing fethishism.
It is term derived from the southern term of endearment that is laughingly used to describe their friends of making a stupid decision because they just weren't using their heads hence the term"trumpass" refers to a group of voters who were responsible for getting Donald Teump elected as President
when you find out your parents / family voted for Donald Trump and you start to reflect on your past life decisions like when you were 8 and you contemplated leaving your house because your mum took your DSI. And you realise, you really should've left so you would go on a trumpus (leave forever) and you wouldn't have to feel disgusted when looking at your family coz they ruined the whole of america. :))
Me: omg Donal Trump has won
Mum: thats great, my vote counted
Me: Bye mum i'm going on a trumpus *leaves house for 4 years until another president is elected*
