A person who creates a definition of their crushes names on Urban Dictionary. Tends to say how attractive/funny/nice they are.
Usually a crushes name rather than a partners because it's done out of longing and desire from not being with said crush.
Many people have done it, don't worry.
Person A: "Ugh, my crush on them is getting so bad..."
Person B: "Oh no, what did you do?
Person A: "I wrote a definition for their name on Urban Dictionary..."
Person B: "Hahaha, I've done that before. We're both UD Lovers!"
