Gosh, I'm having fun.
So let's see...the laugh in fictional account #1. It could have purely inflamed the child-id of the female that hates to be ridiculed, as Bridgeburner said. The reaction would then be from anger--"you hurt me, I'll show you." Regain a little control. Kajira, if I'm not mistaken, you saw that the laugh provoked an entirely different reaction: he laughed because he knew she wanted it, and she was a little afraid because she knew she wanted it too; more, she knew that HE knew. So the spitting would have been done from fear of that desire, perhaps unwillingness to accept it. Or unwillingness to let him know she wanted it--"I don't really want this, see? This is how little I want it." (This wouldn't need to be mutually exclusive; it could hurt on the surface level of ridicule, and also on the deeper level of "but I really do want this...I wish I didn't, and I really wish he didn't know I do.") Or am I wrong and you just meant she wanted to instigate further action on his part?
I love how complex the psyche is, that we can all find different meaning behind a laugh and a wad of saliva.
