Hi, Mark. 'mud-fight winners' evoked two images for me, the first being nude women wrestling, the second being young and mud fighting in the rain with my siblings. After reading through this a few times I see where both parties are not 'clean' - fighting with a loved one leaves both parties dirty.
I think conveying a sense of domesticity/lovers quarrel would mean adding just a little more to this. It is succinct, but the mud-fight image (to me) does not convey a long term relationship as the title suggests.
