Something that cannot be defined as true, yet is not necessarily false; often has a sense of truthiness
to it when used in the context of a paradox
Person 1: The first person to talk to you today is a liar.
Person 2: That would be you...
Person 1: Exactly.
Person 1: So is that true or false?
Person 2: That's an untruth, because you're projecting properties that can't exist; it's neither true nor false and you're an idiot.
Person 1: Untruth isn't a word.
Person 2: Spellcheck disagrees.
Means 'yes', 'exactly', 'right', 'correct', or 'affirmative'. The first half, 'exacta', is from the Spanish word 'exacta', meaning 'exactly'. The second half, 'malaria', is a quantification of the degree of exaction that one's exacting maintains, as well as the precision of its localized exactability.
The intensity of 'exact' is likened, thus, to the deadliness of malaria, a debilitating disease.
The precision of 'exact' is likened, thus, to either the small stature of a mosquito, or the surgical precision the insect itself uses for the extraction of blood from its victims.
"You'll never guess what happened..."
"No really, guess what happened when I waded out into the damned mosquito-infested swamp. Really think about it."
"You... got bit by a mosquito?"
"Exactamalaria! Imagine that! Next time? Why don't you go get your own damn hat!"
A useful insult to direct at any person who cannot perform a simple task without declaring as much aloud.
Idiot: "I'm gonna go grab some food."
Idiot: "Going downstairs... where's that lamp?"
John: "No one cares, you're distracting."
Idiot: "I think I'll just--"
John: "DAMN IT TWITTER WOULD YOU JUST SHUT UP!?"
