What is the definition of Abacidus?

Alright, let's dive into the world of words with our 'abacidus'! Picture this: Abacidus is a Greek word that means "little knife," but when it gets a bit twisted, it morphs into something more ominous - a word that sounds suspiciously like "abacus," the ancient calculator, but instead of numbers, it's used to describe someone with a sharp tongue or a wicked sense of humor that's as precise as a Swiss Army knife.

Now, here's an unsettling example sentence: "The abacidus of sarcasm always leaves a trail of existential dread in its wake, erasing all semblance of sanity with its sharp, pointed wit." Talk about turning a mundane conversation into a psychological torture session!
