Unit-vectors Memes

You know those three innocent letters just chilling in the alphabet? Yeah, they're absolute menaces in programming. Regular variables? Fine, whatever. Loop counters? Sure, getting annoying. But then you hit i, j, k as unit vectors in 3D math and suddenly you're debugging quaternion rotations at 2 AM wondering why your spaceship is spinning into the sun. The escalation is real. From "cute little loop iterator" to "I need to understand linear algebra again" faster than you can say "cross product." Those three letters carry more trauma per character than any other part of the ASCII table.
