Reckless
If the death of a woman occurs it's because she was being reckless. People don't just die out of nowhere! They have to have done something super crazy to cause it. Right? Yes... right.
Picture yourself watching the news about a woman's death. The word RECKLESS?! pops up on your screen and keeps flashing. Huh, she must have been, you think to yourself.

As you watch the news about this reckless woman you find out that she died from mowing (もう) her lawn. You're not sure how, but now you really believe that she had to be doing it really recklessly to die doing it.
Imagine what reckless thing that woman had to have done to die while mowing the lawn. Eww.
