A type of person (though they refuse to be called a person due to their affinity with animals) who acts as though they have fur growing on every square centimeter of their body, wants to obtain a fursuit, and most likely wears a collar for real animals.
Most furries rant about how nobody loves them, even though a plethora of horny animal-wannabes keep trying to yiff with the lonely furry. This sometimes causes the lonely furry to draw obscene, depressing, badly made pictures of their fursona (animal alterego) bleeding, crying, howling, cutting themselves (even though they might possess aposable thumbs), growling, etc.
Another majority of furries, mostly female, are attention whores. Once their lover leaves them, they become depressed and sometimes do the things mentioned in the above paragraph. Once they decide from the millions of male/female furries who want to mate, they suddenly become the happiest "animal" alive.
The art that furries draw is amusingly/strangely morbid. Furry art ranges from nude bipedal animals having "soft spots" from grotesquely muscular beasts cuddling their male/female lover. I advise staying away from amateur furry art unless you want to develop a tumor. Some furry artists are actually quite good.
Though I've said a lot of horrible things about furries, not all of them are bad. If you find a furry who doesn't want to have sex every minute of its life, there's a good chance he/she will be a reliable friend.
