DFC, or Delicious Flat Chest, is a term used to describe females with flat chests. It is often used by anime fans to refer to certain characters. Because of the increasing popularity in big breasts, flat chests are becoming a rarity in anime, and thus many anime fans actually prefer flat chests. Examples include Shana from Shakugan no Shana, the girls from Lucky Star and possibly Nagato Yuki from The Melancholy of Haruhi Suzumiya. DFC is often related to tsundere or any loli character.
