Morphology
The phrase combines an adverbial intensifier 'head-spinningly' (literally ‘in a way that makes one’s head spin’) with 'complex', so the meaning 'extremely confusing or intricate' is directly derivable from the parts. This follows normal English adverb + adjective composition, making the sense predictable for a learner who knows both constituents.
Etymology
Head-spinningly complex paints a simple picture: something so complicated, with so many parts, that your head seems to spin when you try to follow it. That image of feeling dizzy is why the phrase means 'extremely confusing' or 'hard to understand'.
