What would you like to do?
It's a person who finds intelligence in others sexually appealing, usually regardless of gender.
I suspect it is someone who is attracted to stupidity at the extreme. Someone who is indifferent to intelligence could be either non-sexually inclined, inclined for "normal" r…easons, or inclined to be sexually attracted to ignorant people. That would be extremely unusual and ... uh stupid. Another way to answer this question is to define an anti-sapiosexual as someone who is not only unattracted by intelligence, but threatened by it. This could be just someone who has been traumatized and fearful. Someone just not capable of forming any kind of sexual relationship.
