a very strong, overactive radar, which detects cuteness. People who have the strongest cutedars tend to be females aged 11 to 25. Someone with cutedar has the ability to detect even the tiniest hint of cuteness a mile away. They see the cute side of EVERYTHING, even the most horrible things. Because of this, cutedar can be awesome. But it can also get a little full on if you're not careful.
If you would like to improve your cutedar, I would suggest watching excessive amounts of any kind of anime. Trust me, it works!
