Take a sentence like:
I'm not sure what to make of the のはな part. I'm not even sure they're all particles. I suspect the な might be a negative. I'm guessing the の turns the first word into a noun, like "that sort". So, maybe it's saying "If that sort of (noun) wasn't こう..." But, I'm not familiar with a word こう. 子, yes, but...
The context is, a character talking to another character after thinking about the other forgetting to cut his hair. Full bubble: だったらさ! そういうのはな男だったらこう｡｡｡ The other person then seems taken aback.
