Someone that just makes you light up inside, and is so adorable that your heart melts. Someone that she. You see them your stomach gets butterflies, and does flips and you just turn into the definition of joy. The feeling can't be described, it just happens.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
