Chest edges are difficult = nipples are hard.

I'd say the same. Looks like OP tried to mimic running text through a translator and getting the wrong homophone. Same thing with "image familiar" instead of "image related".
I think it's more metaphorical. Both the "edges" and the difficulty. Don't know what it means exactly, but I get a feeling... It's like fine art.
Truly one of the green texts of all time.
