Brain-paralyzing
A level of difficulty so extreme that your brain literally screen-freezes like a broken Windows 95 computer. It describes a task, exam, or situation that is so over-complicated that it shuts down all your cognitive functions, leaving you staring blankly at the wall for hours. This is the unofficial C3 English vocabulary for "extremely hard."
Person A: "How was the advanced calculus exam?"
Person B: "It wasn't just hard, bro. It was completely brain-paralyzing. I forgot my own middle name during question two."
