A girl who has 2 different personalities; 1 which is normal, the other where she is a sort of 'animal' that makes noises such as: "waaaaa!." The noises are used as a defense mechanism for objects that aren't familiar. When a Deanimal is under control she can be quite loving as she will nuzzle with the inner arm of the owner. But beware, she can trick you into thinking she is quite cute, but when your defense is down she will trick you into one of her mind games.
Dude you need to get away from Kelly, that girl is a deanimal, you just don't know it yet.
