Definition: Someone who is attracted only to smart people.
Sample usage: "She was perfect in every way — a doctor, gorgeous and Harvard grad — but she couldn't define 'sapiosexual,' so we only had one date."
Popularity: Perhaps it's useful as a warning to others that you're insufferable because you can name the date of the Battle of Hastings and arrange four matchsticks so they form a pentagon or whatever else is on the Mensa quiz, but you'd just sound smug and pretentious. It's not like anyone is moronophilic, you know.
