Trait: A distinguishing quality or characteristic, typically ONE belonging to a person.
it's something natural -.- it DOESN'T necessarily have to be INHERITED.
Besides, I don't see where did I mention that it's cool or good. it's only humorous, a different kind of "I don't take crap" humor ^.^
A natural trait that came naturally -.- you can't be intelligent, you can't be sweet or rude or whatever it's all natural, you don't specifically have to inherit them.
Ps, if you btw think they aren't, I suppose what do you even mean by knowing them XD
