Simple... You find brains sexy.

Yet another way pseudo-intellectuals try to distinguish themselves from society.

Pretentious and attracted to likeminded folks

In short, sapiosexual can be defined as someone who is attracted to the intelligence that another person displays. In other words, sapiosexuals are aroused by smart people. Interestingly enough, though someone can be physically attractive, if they appear to be "empty-headed," so to speak, then it's an instant turn-off to the sapiosexual. When it comes to sapiosexuals, it's what's on the inside that matters the most. You could be the best-looking person in the room, but a sapiosexual will only be interested in you if you meet their standards in terms of intelligence.

(adj) A form of sexual orientation characterized by a strong attraction to intelligence in others, often regardless of gender and/or conventional attractiveness.

(n) A sapiosexual person.

Sapiosexual: apparently it suggests that a person is attracted to another person's intelligence and wits, rather than their physical appearance. I'd strongly suggest for the term to be replaced though, because of the connotations it carries; the Latin and Greek origins of these kind of words tend to make them universal and they rapidly get used all around the globe. "Sapio" might both mean "to have sense" or "to taste" in Latin, but it also means "rotten" in Greek, therefore the word hints at and sounds etymologically related to necrophilia and/or caniballism.

Someone who '''''''sexually attracted'''''''' to '''''' intelligence''''''', and apparently isn't sexually attracted to anyone until they've found out what the person's IQ is.
