confusing set-up; puzzling method
Internet slang for a baffling or inexplicable design, specification, or way of doing things, often with a critical or exasperated tone.
I'm really struggling with this app's baffling design.
Another update with puzzling changes has arrived.
Compound of 謎 (なぞ, 'mystery') and 仕様 (しよう, 'specification, way of doing'). Likely originated as internet slang to criticize confusing software or system designs.
