Thumbnail Hottie
When browsing friends networks ( like Hi5 or Facebox) and you see a Hot ( Mae or female) and you get hyped because they look hot, then you click on the picture and realize that they aren`t hot at all
I was browsing Hi5 and saw a smoking hot chick, i watched her pictures and realized that she was only a thumbnail hottie
