Haupy
A person who, when doing the sad face for his girlfriend either for attention or for forgiveness, is so adorable it makes her heart break and devour his warm cozy cheeks (i.e. you end up just wanting to hug him and kiss his cheeks). Also a reference to something really sad.
You see your boyfriend/girlfriend with a really bad cold and looking sad so you say: "Why do you look so haupy??" :(
