noun. Ask the perturbed, the peeved, the pained, and the chagrinned. They know what it is to argh one out.
Real citation: “Another cause of arghitude is that when you use macros like this, you're sort of writing in your own extension the C language, which means that your code is non-standard, more complex, and somewhat less readable (though it's somewhat balanced out in this case by the readability advantages of forall over for)."
Made-up citation: "I've had so little arghitude this week... The sun is shining, the breeze is calming, my work is getting done, new ideas are flowing, and even the toilet has a rainbow. Did I die and no one told me?!?!?"
