A slap is or can be regarded as a insult especially at the opening of a fight , but take into consideration that as women while we do punch , throwing an open volley of blows rarely are as concentrating unless your use to throwing punches or had boxing /MMA training or like in the case of my hubby who served taught me to punch, but during a rolling “ catball” situation then solid open face crack to the cheek has amazing effect, in some cases can take a rivals breath at the force, but best part of a slap is landing an open palm then a backhand follow through , naturally if you have pinned your rival it can go from beating her ass to toying with her and embarrassing her as well as cause tears, cut lips and bloody nose , slap to breasts goes without a explanation it hurts bad
