Serious question. I don't recall this ever happening, but what would happen if a punch hits a woman's boobs? Is it just like a more well defended chest strike? I'm sure it would be painful but we disregard that factor a lot so in terms of actual damage I think it would be largely ineffectual, right (given the punching person isn't a lot stronger than them, of course)? If it was effective i would think it would be used more.
