"By mixing magic with perfume you have a created an alluring magical scent, which partially disorients your enemies making you harder to hit."
Given how much of a punch to the nose a lot of modern perfumes are - to say nothing of medievalish ones which were often meant to cover up poor hygeine and thus even more pungent - I don't think magic would be necessary for this. :P
Sarcasm aside, most of those trait names (and many other things) are meant to be referential rather than fully descriptive. ("Raistlin" is the most obvious one in this regard.) You can explain them however you want.
I suppose that they could come with descriptions that suggest a few different possibilities, "Perhaps you were... or maybe you..." style. That's a end-of-development polish thing though.
